The viewers have chosen and this weeks video will be about solving Honda idle problems. I'm really not surprised as I get a lot of questions and requests about this very subject. Here are the links I promised in the video that will help you address specific issues mentioned in the video.

Hopefully when your done checking all that stuff out you will have solved your Honda's idle problem, if not leave a comment or send me a message and I'll see what I can do just make sure you have tried all the stuff in the videos first as that saves me from typing so much.
I also want to add my "Idle Speech" into the mix here: www.ericthecarguy.com/forum/8-...
There are a lot of things that can contribute to an idle issue, in fact in the end it may still be there to some degree because of the nature of that engine however here are some things to start with.
First start with a good tune up, use NGK or Nippon Denso plugs, don't change the wires if they are OE, if they aren't OE you might consider NGK wires as they are very good and less expensive then OE. A quality cap and rotor should be good. A new air filter also helps.
Don't change the PCV valve, if you see an aftermarket PCV valve in there put a Honda in, believe it or not I've seen idle issues caused by aftermarket PCV valves, the OE's last just about forever so you can easily justify the expense.
Next a good valve adjustment, this goes a long way to smooth out the idle if done correctly, mess it up and things can get a lot worse though.
While you have the valve cover off check the timing belt tension, if you feel a lot of slack this can cause the cam to 'chunk' as it spins causing a rough idle. If you think the belt has been on there for some time then you might consider changing it and resetting the tension properly, if it's not ready for replacement you can reset the tension to take up the slack.
DO NOT adjust the idle screw under any circumstances, it is set at the factory and that is the reason it was sealed in the first place. If you find that the seal has been broken and you have a low idle and you have done all of the above then you might turn the screw out a little to see if that helps the idle but only enough to try and bring it back to where it was before it was adjusted in the first place.
Last clean the screen in the Idle Air Control valve, this can get clogged up with carbon over time and cause the flow through it to be restricted which can cause idle issues.
If you still have a 'rough' idle after all of this THEN look to the engine mounts as you want to be sure the engine is running correctly before you go for those as the one in the back is a real pain to replace.

Barely going to watch this video. 13 years old and it’s still helping people out.
Yup, there is still people watching your videos from 9 years ago lol 😆 thanks for teaching me
Yes sir I
Am
Same 🤣#idleproblemsonmyrsx#vaccumeleaks
Yup
Bro my 1998 honda is having trouble staying on. You guys think it is an idle problem? It's not the batery or alternator for sure
@@22Alex47 My 1994 Honda Civic had the same issue. I believe it was the voltage regulator that I replaced and it worked beautifully. In the heat the old regulator wouldn't work, I was told it was because a wire was likely broken and would expand away from a full connection. Good luck!
“At a dealer you don’t make a lot of money cleaning things”. A truer statement has never been made.
When you guaranteed your work you don’t stuff around with repaired parts. They’ll come back and bite you.
Eric is one of the best, if not the best CZcamsr for Honda cars. I've began my learning journey with him, I am now a self proclaimed Honda master tech. 😁
I could freakin kiss you Eric!! This was such a headache on my Honda Civic. I failed smog terribly because of that cold-start idle air control. After a bunch of replacing sensors and crap I took out that idle air control and turned it all the way in like you showed and it fixed it completely!!! Passed smog perfectly!! Dude I'm so happy! Thank you for saving me so much money. Guys! Subscribe to this guy! Like his videos! He is giving great information for free. He's like Beethoven on the engines. Thank you again brother! Holy crap that was load off my shoulders.
NoFace thank god that worked..I’m gonna try this
What year honda civic?
so it doesnt really mean I need to replace the throttle position sensor?
Maybe brotherly hug instead of that earlier suggested kiss😉
Thanks Brother!🤗
THANK YOU ERIC!! 10 years later and this video is still super helpful 🙏🏼 I hope you’re all settled in to your new shop now by the way
Wow thank you so much! My idle has been way too high and unpredictable since I purchased my 1990 Accord, so I followed your simple instructions and I opened my fast idle valve and found it took quite a few turns to make it snug. Now, my car idles perfectly at operating temp! Thanks again! 👍
Thank you for being a professional (understanding the system and using proper troubleshooting to solve problems), as well as a teacher to those of us interested in learning how professionals do things. +1
XX "I Don't alwayz work on CARS, BUT WHEN I DO! I watch EricTheCarGuy!!!........Stay Dirty My Friends! XX
12 Years later and this video still helps find my problem, thank you 🙏🏽
I surprised myself, all because of the confidence you gave me in several of your videos. I did all of the spark tube seals on my wifes 92 accord because of you. Looks like low coolant is the culprit today. You're a gem Eric.
To add to the last comment 10 years later you are still the man. Dealing with a 94 1.6 civic at the moment and you have taught me tons. Odometer stopped at 350k . I like the way you teach, I do hvac and as simple as a stink bug, can make the contactor on your outdoor unit not come on. Thanks for true honest advise.
Lol I just bought a 1991 honda accord lx coupe for my first car for 350 bucks because it had this issue and the guy thought he had a blown engine and I didn't know if it was a blown engine so I bought it knowing I might need to look online for a used engine. instead I found articles online explaining this and got it fixed. idle issue problem fixed, new back struts, and a little cosmetic work later I have my first car for less than 1000 dollars.
ZDubs Hey I got my first car too! It's a 1992 Accord Ex r coupe. Same issue with the idle. Got it for 300 bucks as well! Starts at 1600 rpm then goes down to 800 rpm and starts to vibrate. What fix did you use?
Good job man I wish all younger people had that drive, keep it up
My $450 '03 civic will have its 1st year birthday with me in month...biggest job I did was change the radiator lol
Hey! That was my Honda. Give it back!
Been having problems with idle too, replaced a bad IAC valve part costing $240 (old one had a torned in filter screen) at O'Reilly's did not fix the problem, high idle at 3000 rpm for prolonged periods, then just watched this video and did as instructed- BOOM PROBLEM SOLVED. RPM at startup at 2.5! Went to 1000 in just minutes. Gears shifting smoothly. Engine sounds way better feels better. Thank you Ericthecarguy.
This is my 2nd 1991 Honda Civic Hatchback I'm a girl who loves to work on her cars. Thanks for this tip Eric. I went to smog my car today mechanic said it may be idle air control valve and ran into your video. I'm gonna tighten this tomorrow 🙏❤ Oh if anyone wants to know YES it passed smog mechanic was in shock 😅 My hubby passed away 4 years ago Dad 6 so now I must do my own repairs. But it is what it is. Thank God we have CZcams and Eric who wants us to save money on parts ❤
Eric thank you for all the videos and work you do to help those who are uneducated on these issues and are in great need,your a good person and people like you help so many of us who are in need...THANK YOU!
just tightened the fast idle valve on my 92 accord and she idles perfect now! I love you
12 years later and it’s helping me, my idle goes up and down when it’s in park for too long or a little or when it’s just sitting
You ARE the man! Thank you. After reading many other posts on random forums i ended up replacing the MAP sensor, throttle position sensor, pcv and grommet (worst job). I was at the end of my patience when I watched this video. I then ran through the tasks you suggested. Once i pulled the IACV my problem stuck out like a sore thumb. Clogged coolant port and hose. 4 years ago I was told to use GM coolant tabs to help with the typical antifreeze smell. The tabs worked great in taking care of the tiny seaps where aluminum touches aluminum but that gritty material pooled in the IAVC. Moral of the story CHECK WITH ERIC FIRST!
Eric...your videos have saved me multiple times already and I've only been a Honda owner for three days. Keep up the good videos, bro. I am a fan for life.
Thanks, Eric. Had to change a heater hose and the idle immediately went to Hades. After burping the cooling system, idle smoothed out.
Can you clarify a bit more on which hose? Having idle issues. Changing my IAVC didnt help. I had a coolant flush months ago but didnt have idle problems until months after that day.
Myself and my 95' Prelude also appreciate the love. Thanks Eric! You the man!
Eric. that worked for the hunting idle on my 1994 del sol. I tried cleaning the iac and that did nothing. turning that all the way down completely fixed the hunting idle. this was the only place I saw this suggestion as a possible fix. and it worked like a charm. having the car idle up and down until it warmed up drove me nuts for years. you are the man, man.
Thank you so much! I just did a valve replacement on my 99 CRV by myself and your videos helped me all the way! I really appreciate what you do!
Thank you very much, I wish everyone could have a mechanic like you near by.
Keep up the good work !!
Still helpful in 2019! Eric is awesome!
Eric, Thank you so much. I started watching for the Fairmont project, and since starting watching, I currently only own Honda products. I've loved them, but was not familiar with how some of the systems work - your videos have allowed me to fix several issues over the last few years. I try to remember to both like and comment on any of your videos I watch to help with CZcams metrics and monetization issues.
Your tip to check the code first is great advise. I changed the starter in my Honda Accord, which meant removing the manifold and lots of other stuff - and neglected to hook the wiring clip back onto the mass air flow sensor. reading the error code of PO102, quickly told me that was the issue and I was getting ready to troubleshoot with a multimeter, when I saw I simply did not clip it back in. What an easy fix, but, really hard to see that it was unclipped. Thank you EricTheCarGuy!
Awesome. I just did it on my wife's 99 Honda Accord and the idling smooth out. Thanks Erick love your videos.
Stay dirty
Thank you for all your help I truly appreciate you taking the time to show all of us what you do.
Eric, you are Still making a difference in the lives of your CZcams followers! Thanks for the guidance and words of wisdom. Timeless information bro! Thanks!
Sir you are a legend, I Followed your instructions on the FITV and after weeks of loking for an answer I found a solution.I purchased a 1996 Honda accord for co worker and he told me that the car had this issue. I cleaned the Idle control valve it made it better but the problem was that every time I start the car in the morning it would start revving like crazy. I Watched this video and tightened the FITV I can say it worked!!!!. Its been 2 days and it is WAAAAY different. Sir thank you
EXCELLENT! I can't begin to thank you enough, Eric. :) Subbed, looking forward to now learning more. Great job, thanks for putting your expertise out there for us poor and or frustrated drivers.
thanks for this old video Eric. it's nice to have these to come back to.
subbed....as far as speech, tone, camera angles, and descriptions you are by far the best you-tuber to learn from.
You're the king. Rough low idle, lasted about a day and then check engine light. Checked coolant and it was low so since I had some on hand, figured I'd try that first. To my surprise, it went back to smooth idle within about two minutes. Thanks bro!
Thanks for the help! I know it's been 5 years but these types of problems are still happening. Mine was in the fast idle valve. It was a pain trying to get to it due to my motor being in the vehicle, but it is possible. It took a while to bottom out (that's how loose it was). Put everything back together and the cold start idled normal!!! Thanks again!!! (:
Eric, you are the man! Thank you for teaching us how to take care of our Honda’s! I have always watched your videos for DIY tips on my Hondas. Thanks to this video I was able to fix an idle issue on a 97 prelude that I just scored for 1600 bucks (fast idle valve just needed tightening) 🙌🏼 Thank you for sharing your knowledge and guidance
Thank you so much! One day after work my Odyssey started surging while idling and even when driving, I was a bit nervous but thankful for your video!
Excellent tip Eric! It solved the idling problem on my Civic 93! Did realized the reason the plastic cap losens out.... the O-ring of the plastic cap, next to the thread, with time hardens up (looses friction with aluminum body) and with engine vibration allows to unscrew eventually again. Replace with a NEW O-ring!
Hey eric thanks for your help and taking time to make people better understand diagnosis procedures with the access to your detailed videos, I'm wondering if you could talk more about the access to the iac and fitv that seem to be fed by small ports in the throttle body and what happens or what should happen when restricting air flow to either or both and if it should at all sound like loud suction at any giving point similar to a large vaccum leak and maybe talk a little more about the idle screw on the throttle body and when you can decide to make adjustments when nessesary, thanks for your help, take care
Learn a ton from your videos Eric, thanks a bunch! I get smarter each time. The lesson you give in the end about taking time to diagnose before spending money is something I wanted to echo a hundred times. Great information!
Been watching your videos for about a year now and just stumbled on this one after not driving my del sol cause I thought it was a bigger issue I replaced the IACV and it did nothing and I opened the fitv it was so loose it almost fell out now it idles at about 6-700 rpm steady and quiet
Thank you
Hey man, i did what you described and showed in this video on my 98 honda crv and all of a sudden i was wishing i had all the money back that ive spent on it in the last year because of this idle issue, i had to wind mine back in sure enough and it has ran like a new car since, i was blown away that it was something so simple
Hey Eric! Appreciate the info, just wanted to know, can the IAC Valve prevent a motor from starting up as well?
Eric is one of my favorite utube Honda doctor!
Happy new year Eric! I was wondering about your update videos on CZcams for a while, but when I was searching about some issue on my CRV (RD1) and found this video. Now, I was going through descriptions on the video, and somehow I went to your website. And then, I just clicked a link to your face book (that I don't use) for no reason, and I found your recent short videos including your report about your update about finding your new shop. I am grad you are taking a nice winter break but moving forward. I will wait for your new post here !! BTW, Thanks for this video👍
Thanks for the vid. I couldn’t reach my idle control valve to tap on it in my 96 civic 1.6L non vtech. I pulled the ICV and cleaned it because all the parts stores were closed. Put it back together and bled the air out of the coolant. Although I couldn’t find a breather. I just ran it like you said and squeezed hoses until all bubbles were gone. Idle problem solved. When I turned on my a/c the idle would almost stall the engine then run back up. Now it’s good to go. If I have any more problems I’m changing it out.
You sound so sincere...Dude...plus you earn nothing from it...God bless you-Thanks....

I have been experiencing vibration on idle and loss of
acceleration .. but only after i been driving it a while, wither its a warm day
or not.less than 2 weeks before this, i got my head gasket replaced
as well as new timing belt and pump and spark plugs and a new rad and cap. My
check engine light did come on about a week after the repair and it was a code
for crankshaft sensor, this lasted abut a week at times going off and back on
until finally never came on again, so i used OBD and reset the ECU but im left
with the vibration issue and loss of power on acceleration.
Also in park or neutral the engine revs great no loss of power or
anything
timing may be a hair off?
I'm experiencing almost the exact problems. Did you find out what the problem was by chance?
not yet its still drivable.. but i will later on
vibration is comming from the idle dipping so low and recovering. This effect will be enhanced if you have bad motor mounts.
I got same warm engine problem then it will crank but not atart i need to try like 5 times til it does start up sometimes
.. other days it runs like new
Eric, I have been beating my brains out trying to figure out why this 97 Civic is idling so erratic. I have looked at many videos and read many articles and NOTHING worked. I was about to go and buy a new Idle control valve for $180.00 and then I came upon your video and I thought what the hell, I will look at just 1 more. After watching it I then went to my tool box and found the oldest nastiest screw driver I had (I did not want to use 1 of my Snap On) and tried your little trick. I could not believe it. It worked. Just wanted to say thanks for the video. I will come back and ck out other videos of yours very soon.
Hi Eric, crazy that I'm watching this Honda idle issue again after 10 years. My son have issue with his 97 civic so I come back to your channel. Funny how 10years make a difference. Still looking good. Hehe
Excellent video! I appreciate the fact that you don't want us to just throw our money into parts & want us to actually get a diagnostic / codes when engine light on. I actually own a 2000 Honda Civic & have been experiencing this particular idle situation. I'm thinking the TPS as well. First chance I get, getting that good ole screw driver & giving it a tap or two while engine running. Thanks so much for all your great videos. You rock! P.S. Yes I had a simple diagnostic done, but said all cylinders misfiring. LOL! And as we all know that could be a bunch of things, so not playing the process of elimination game :) (I'm a smart girl...my Daddy taught me well) Thanks again.
Yeah, Eric's a genuinely good and helpful dude. A youtube subscription must!
I subscribed a while back, so glad I did.
Zachariha Rachel I have a 2000 cr-v and I'm going through the low idle problem as well. I've been thinking the distributor is bad. My check engine light flashes while driving and my reading was the same ( misfire ) I will have to try this tonight. Also it will rev up to 3000 - 4000 rpms before shifting. Did anyone else's do this? Btw Eric you rock. Thank you so much.
May 2019 this video helped
Eric, the IACV is now becoming a common problem for the Element owners. I have passed on what you taught me when I was battling with my '92 Integra and saw this video. Red Martin just wanted to say Thank You!
Eric you Rock!! I’ve got an 87 Acura Integra & The FITV adjustment did the trick. Cold start up idle surge gone!
Hahaha, "The rescue worker, that got there a little too late" xD
I must be 🤪 but I can’t seem to figure out how to get to the fast idle control I have a 1997 Acura 2.2cl
Hey Eric just wanted to say that I highly enjoy these videos and I have been watching them for sometime now I have learned immense amounts lol of k now ledge .. lol.
Thanks for making these videos and stimulating the brains of many. 👍
Thank you very much. I found out the problem of my car after a long struggle... I'm following you 11 years after the video was posted. Thank you
one thing I find weird is my 96 civic when warm, when you push in the clutch it stalls makes it fun at stop signs and red lights
Mine does the same what did u do to fix yours
I'm currently in this same situation. I've burped the coolant system, cleaned the IAC valve and currently about to do a vacuum leak test with a propane torch. Did either of your two have an issue with the idle barely fluctuating when sitting at a light and upon take off have it (A) have throttle issue when accelerating ie bog, erratic? Turn ignition off, turn ignition on to bump it and have it clear up until the best time came to a stop for longer than 10 -20 seconds.
(B) die on you and not start back up for at least a minute?
Also could you avoid it from happening by gently applying throttle on and off while stopped and not have the issue arise ? These are all examples of my current issues in a 99 Civic ex
@@859don any luck on finding the problem? I have the same problem
@@donwyatt8753 I've come to the conclusion it's the IAC itself. Haven't replaced it as of yet. I did put a new ignition switch in (mine went bad) and it didn't make any difference. Therefore IAC has to be the gremlin. No leaks and good cylinder compression on all cylinders.
your voice matches with that of George Clooney
I recently picked up a 2000 prelude type sh as a project/learn stick on car. The h22a4 engine in it does have the FITV(fast idle thermo valve). I've had idle issues with the car since getting it like rpm surging(1k-2krpm up and down) a minute to two after start up. I took apart the throttle body to get to the FITV and removed the valve, took it apart and cleaned it all up and it runs 1000x better. No more high idle above 1200 it stays consistent at 800-900, and no more rpm surging. THIS GUY KNOWS HIS STUFF!
My 1992 Honda Accord idles up and down while in park. When I'm driving it does just fine, it only does it in park or neutral. Why? Also, car only goes into gear while it's off meaning I have to put it into reverse to back out of my driveway and once I get to the end of the driveway in order to go forward I have to turn the car off, put it in first and go, and the same thing applies when I stop at red lights and stop signs.
Kianna Petty idle control valve or prob map sensor..
Kianna Petty check coolant if its low
I have a Honda accord ex need to change front wheel axssoul
What should I do if once I turn on my Ac my idle drops as if it's gonna die, and while I'm driving as soon as I let off the gas the rpms drop to quick (almost like a second handbrake). Also I will have low power when taking off but sometimes it would get short surges of power out if nowwhere. But once I turn my ac off everything is back to normal. I drive standard by the way
+Psycho & Keith my also same like you car problem -.-",now you fix already ?
....no ppls reply
+Lee Sky there is one fix, Ac delete;) haha
had this problem but I got a check engine light fixed the code and it fixed that issue. on mine if I ever revved it would drop down to 300 rpm. it would want to surge buckle. also when I turned on the AC . still does it but now not as nearly bad. also manual 2.2 acura cl
+Psycho & Keith most likely electrical issue.
ETCG, you are a true blessing to everyone who views your videos. Thank you so much for being so awesome. Stay dirty man.
Tried this on my 1990 Prelude, thing was surging from 1-2 consistently and driving me crazy. Did this in about 3 minutes and I haven’t had it surge once since. Thanks Eric
Hey help me out. I have major low rpm it is near the zero. What should I do?
I have the same problem when I floor it and run the car hard then when I drive normal and come to a stop it idles really low
exact same problem
tap the idle control valve. i had the same problem and that fixed it for me
check the throttle cable tension make sure that's snug and if that doesn't fix it try unplugging the cooling fan switch
Hi, I have a Honda CR-V 2000, 2.0... I have replaced the Electronic Idle Control and I am still having the same problem with revs going up and down in idle. I have no check engine light on, So what I am gonna do is try the Fast Idle Control, Air in the cooling system and vacum leak... Thanks so much!!
I had the same prob, It was air in the cooling system
I'll try that! Thanks!!
11 years later and still the best advice iv found thank you much
Very helpful explanations and great presentation. Not sure it's going to fix my problem, but these ideas are certainly empowering. Thank you
Can someone help me with my problem . my honda accord 2003 v6 has an low idle . There is a check engine which reads low idle . i changed the spark plugs because someone told me its because of it but nothing changed . and because of the low idle i cant turn on my a/c . every time i have to stop on a stop sign i have to keep my foot on the gas .
Thanks
I have the same issue. mine will die when it in Park or at a stop
+Randy Fought you need to check your check engine light and look up the codes on Google. don't just change parts and hope you fix the problem. I'm guessing your car problem is within a vacuum leak, tps or map sensor.
+D'Faro it was not a leak or anything . just cleaned the choke and its working fine . . thanks for the reply guys means alot
im having the same exact problem did u get it fixed?
+D'Faro i dont have a ch
I wish I found you before I took my car to the mechanic and got sodomized. Nevertheless, thank you so much for the wisdom you imparted to an ignoramus such as myself.
Dude I totally got a date with liz for fixing g her car thanks to up
Thanks for the video, it basically allowed me to fix my Dad's '97 Accord idle issues. The idle would surge, then settle, surge then settle. It got so bad he could barely drive the car more than 25 MPH. I replaced the IACV. Didn't fix it. I bled the cooling system. Didn't fix it. Then finally I took off the Fast IACV and screwed that piece back down. THAT FIXED IT. My dad says the car now runs better than he ever remembers it running. Thanks!
Greetings ETG and thanks for the information and philosophy. I had a problem with the idle (hunting) on my Odyssey 2001 4 cylinder, the manuals I found all referred to a throttle adjustment screw on the throttle body but this model (RA6 4 cylinder in Australia) does not have a throttle adjust screw. When I removed the IAC valve (IACV) for the second time and cleaned it, this time I separated the electronic component from the IACV body and cleaned the valve shaft and case, this fixed the hunting problem but idle was 1100rpm instead of 700rpm. I noticed that the IAC electronic component screw slots are elongated and allow a small clockwise / anticlockwise (maybe 5%) adjustment. I put it all back together (the hunting problem resolved) and sure enough, a small but significant idle adjustment. You are an inspiration.
Your instruction on how to adjust the fast idle thermal valve isn't correct, or should I say was misleading. By your example you say to snug it down, but due to the location of this valve, most people will do this work with the car off. If you snug it down cold, then you will get no cold air bypass, as the valve extends when coolant warms it, thus sealing off the bypass air when warm. So, to clarify, if the car is cold, DO NOT tighten down the FITV all the way, it needs to allow some bypass air. The valve will heat, extend and shut off the air if working properly. The simplest suggestion to tell if the FITV is your issue, is with the car idling, inside the throttle body there will be two holes on the left INSIDE the throttle body, one high and one low. The lower hole is for the fitv. When at normal operating temp and the intake removed, plug the lower hole with your finger...if it is pulling vacuum, the FITV needs adjusted. This is the most common cause for the bouncing idle.
Eric made that test clear in his video as well as instructing us to watm the motor up b4 adjusting.
EVERYBODY CHANGE TPS SENSOR 40 BUCKS ON EBAY!!!!!!!!
Thanks,your video gave me some good info to figure out my rough idle didn’t stop it but gave me something o go off of to hunt down the culprit lol,my son and I both have been working on our element and have to say turning wrenches with your kids is the best bonding time in the world plus gives them a good set of skills to help them in life.
hands down the best video i’ve seen on this particular honda issue. thank you so much for this
I bought a 1996 Honda Passport 3.2 4wd 217k when I bought it little over a year ago 253k now runs pretty decent just wanting to do different types of mods more HP upgrade .... Suspension lift .... this is the first Honda ever owned had a few problems but nothing out of the ordinary still has a few bugs but I'm working them out I would like to know where to find info so I can have more knowledge on my truck .... I watch ur videos every chance I get .... great information .... thanks again Eric
Thanks for sharing your expertise ETCG! you are always so much help when i am staying dirty... You Rock!
I checked everything you recommend ..and my air idle problem was due to a bad ECU.. swapped the ECU..and my idle problem was fixed immediately..
Great video 👍..
Ecu? I have heard about people swaping ecu and it ran rough causing the next person who buys the car some headaches.
3-10-21 and still watching these videos! Appreciate the knowledge, a lot of help!
You're the best. Explained everything to me and I've watched a ton of videos but this one made me understand everything. Thanks man.
My friend Eric told me about you a couple of years ago. Now that I'm looking at a Honda, this video came up. Thank you for this information. I will check those items out before getting the car.
Thanks for all your great tips! I really miss the days of a simple 1 or 2 barrel carb!
thanks so much Eric the car guy I have looked so much on the internet and found very little information on the idle high low problem this video answered so many questions and I am 90% positive it is either the fast idle or the idle control valve thanks again Eric I'll be subscribing
He is no hand down the best car guy on CZcams, nice videos great angles and doesn't over explain
Thanks Eric! This video inspired me to keep going and I solved the issue! Filthy IAC
One thing -- I tried tapping the IAC with a screwdriver to no avail, but it did end up being the issue. For others with this issue: do not count on tapping on the IAC to free it. I cleaned it and it has been working for 6 months.
Another component that can cause idle issues is something known as the Air Boost Valve. (It's suppose to help start your car in really cold weather ... really cold.) Anyway, in my 1991 Integra LS hatchback 5-speed it's located just to the right of the dashpot throttle lever. If it starts to fail it can cause a surging idle as it tries to feed more air into the intake. It's also daisy chained to the dashpot via a teed vacuum hose. You can either remove it and block its port to the manifold or remove the 2 hoses it has going into it and just close them up with vacuum plugs. One of them, the long piece, being the teed vacuum line to the dashpot, can then be re-used as a direct vacuum line to the dashpot as one piece of hose. The other larger hose should be plugged at the valve and on the top of the manifold. So what did it accomplish?
1) My idle surge is now gone.
2) With the Air Boost Valve vacuum line no longer on the same vacuum line as the dashpot, the dashpot now performs much better. Smoother engine running when coming off throttle. Smoother shifting occurs as a result; revs don't drop so much or so quickly. Nice. And no change in cold starts.
So I offer this as a consideration. If it doesn't work you can always restore everything back to how it was quite easily.
This totally just worked for me I had and up and down idle problem I tapped on that unit in your video and now my car is idling just fine no more up and down thanks very much Eric
11 years old video still helps me out,thanks eric
Very very informative I have a Honda civic EX manual Transmission and I am experiencing the fluctuating aisle and you were right I ran right over to Advance Auto and bought another bottle control valve so before I purchase it I will do as you stated and check the higher idle component and see what happens and thank you again great video
Hey Eric, I followed all your steps just like you said and used process of elimination and it turned out to be the high idle valve i tightened it back up and runs perfect now again.
Most dramatic mechanic speech ever,... Give this man an award... And thanks! Same issue, about to tackle it.
Awesome presentation. Great advice as always. My Honda 92 is still running well for my son's college car, but the idle slows almost to a stall when the air is turned on, (which still, after all these years, blows cold). I'll give your possible fix a shot. Thanks!
Beware of auto technicians who typically have only a passing knowledge of refrigeration when letting them service your A/C. And check the temp of the air coming out the vent before you take it in so if he screws it up you'll know.
Hello Eric first of all, I would like to let you know that I enjoy your informative videos. I recently did a throttle body cleaning on a 2009 Honda CRV 2.4L four wheel drive. The throttle body was definitely gummy & dirty. The idle had a slight shake and hesitation coming to a red light or 4 way stop before the air intake cleaning. Now, the SUV runs smoother but with an abnormal high rpm above 1000 parked at idle. Also, the vehicle surges up & down at cold starts. Once the engine warms up, the RPM settles at around 1,200 but with a check engine light & engine code P0507 for idle air control valve at high RPM! Gosh, I hope I didn't damage the IAC. I tried everything from disconnecting the battery for 30 minutes, doing the reset/relearn Honda procedure including driving the vehicle for a while on the streets & expressway and I even bleeded the coolant system from any air pockets since I disconnected two coolant lines. But that didn't help out either. I cleaned the throttle body without removing the assembly and had someone hold down the gas pedal to keep the throttle plate open. Hopefully, you or some of your fellow mechanics could give me an idea in what might be going. I'm a diesel mechanic employed to work on transportation coaches. Been a while that I worked on cars. Thanks for any advice you could give me.
Thank you so much for this video, it helped me fix/service an accord's 94 FICV...
i got a 39 accord 2.2 liter just did a engine swap do to a blown engine replaced the f22a1 with a f22a6 didnt have the right ecu so had to use my old 1 had to change the intake over and the exhaust for that reason . but anyways car was running good started have a idle issue up down up down watched you video ended up adjusting the fast idle valve and seems to have fixed my issue. will know morn in morn ty
I had a surging Idle problem in my B20B 95 Integra and this WORKED! Just had to tighten down the fastle idle valve cuz it was really loose. Was a pain in the ass to get to but it worked so thanks Eric!
