On todays video the hatchback finally gets the pesky idling issue address, and FIXED. After all these years I finally decided to get off my lazy ass and take a good long look at the problem and some common things that can cause it.

Self-tap screw to the rescue 🛟!! 😅
@sawkpawn4071 Lol if it works it aint dumb!😅
(Its pretty dumb…but it did work)😂
I had the same problem!I removed the throttle body while watching your video and did the same procedure like you showed and it worked! Thanks 👍🏽
this helped me figure out the things i need to do. my surge is so bad & annoying especially with the exhaust i have. this video is really helpful & tomorrow i’m gonna check everything you checked
@Chozohh Glad i could help!👍 Best of luck with your fix, hopefully its not like mine..lol Mine had pretty much every possible issue to cause an idle surge😅
I had an idle surge problem on my 2001 Honda Accord V6. I swapped every part, IACV, throttle position sensor, upstream and downstream O2 sensors, cleaned the catalytic converter, cleaned the intake manifold, new EGR sensor, new throttle body, new intake tube, new MAP sensor. When I would disconnect the MAP sensor, the surge would go away, but it would run rich. I took the new MAP sensor back off with the car running and put the old sensor back on. It fixed the problem by reinstalling the sensor while the car was creating a vacuum in the throttle body. I've been driving the car for 6 months now without the surge coming back. When I changed the part with the car off, it still had the surge. Try changing the MAP sensor with the car running
I will try that right now, thanks boss 👍 and i will see if it fixes my issue
Didn't fix my issue
If you take map sensor off while ca running your check engine light will go on
Honda civic '97 D16Y5, '96 - 00 D16Y8 engine:
Idle Speed setting.
[Engine warned at normal operating]
1. If disconnecting the IAC valve connector,
Idle speed should be
450 ± 50 rpm.
2. Idle the engine with IAC Valve connected anf with no-load conditions for one minute, then check the idle speed.
( NOTE: (Canada) Pull the parking brake lever up.Start the engine, then check that the headlights are Off. )
Idle speed should be:
670 ± 50 rpm (USA)
750 ± 50 rpm (Canada)
A set of left handed drill bits will remove that bolt. It will drill in and eventually loosen up enough to just unscrew itself. Also PB Blaster is your friend. Let it sit before trying to unbolt those things usually helps.
Great jod I got the same problem great video great content 👍
Super good video. Subscribed😊
I feel the pain bro i gotta start using that 15 minute job quote it’s too true I got a rd1 at the moment I striped the locking bolt on my outer tire rod and the upper ball joint started spinning turned into a 8 hour job had to buy my freind some pizza for that moral support
Hahaha Yeahh, sometimes thats just the way things go bro 😂👍
I have the same issue with my b16a, it stated when I change my throttle for a 70mm skunk2 , it only happen when I drive aggressively
you did a good job bro
@ebrahimvirus Thanks Bro!👍
Awesome video!
Btw, that's not 500 at 14:07
It's bang on 750.
That first line above the 0 is 500.
My D16Z6 has the same idle surges. I don't think it has an FIV but I'll check everything else.
Thanks!!
Really!?? i was wondering what that first skinny line was, Thanks!👏 yeahh idle surges are annoying, its taken me years to “fix” cause the car will still run regardless…..so i just ignored it!! 😅 Best of luck!!👍
@@projectgoodspeed
Yep! It's tough to have an analog Speedo and Tach show EXACTLY zero, so they basically put the zero mark at around 300 rpm and 6 mph respectively, which is pretty much zero compared to the rest of the scale.
Thanks for the reply!
The car does run but it might consume a little more fuel since the ECU (wrongly) reads the IACV to calculate the mixture.
Other than that, it's just a small annoyance.
Oh and by the way, you could try cutting a slot in that broken screw, and using a flathead screwdriver to remove it.
Or, use a center punch to mark an indent which should keep the drill bit from moving around.
Or, since you've already threaded a screw through it, you could use larger and larger diameter drill bits until it barely has any metal left (it should move way sooner than that).
Just be careful not to damage the threads.
Finally, if you mix 50% ATF and 50% acetone, you get an awesome diy penetrating fluid that could help loosen up any oxidation / rust that might have built up between the threads.
With that said, since it just holds a little cover in place, it shouldn't come undone anytime soon, but if you ever get back to it, or get another broken bolt, you might wanna give those a try.
Best regards! I'm subbing to your channel.
Bro I’m glad I saw this comment 😂. I was about to say the same thing
I had a same problem on my 1996 civic, i change the map and tps sensor and clean the throttle body and nothing change, then i just had to change the idle control valve but was $200 at autozone, i bought one from amazon for like $35 and it fix the issue right up, runs like a new car now even feels stronger.
@stevenguzman2482 Daaamnn Amazon came in clutch!!!!😅 i know i seen the autoparts price at $200 and i was like nahhhh!!!!😂
@@projectgoodspeed yes sir and even i clean the old one couple times didn’t work the same
Hey can you assist me in getting a new iacv. I'm worried I buy the wrong one, 1996 civic, d15b 2 stg vtec. I have similar issues.
I cleaned my tb and IACV but not the fast idle yet. It helped the 'hunting' idle but apparently my AC doesn't work because there's still an idle issue underlying. It shows up at night when I notice very slight surges on the lights.
I don't mind trying a new iacv.
@@joshuafrancis4634 Hello, everything with idle should in the throttle body with the 3 sensor, yes get a IACV I bought mine from amazon for $30 instead of $200 from auto zone and it fixed my idle as i installed .
@joshuafrancis4634 Im not too sure ill be of any help, i dont really know which is the right one soo if your worried about buying the wrong one ill definitely buy the wrong one. I tried searching for an IACV for my hatchback recently and i couldnt find one that looks similar YET amazon says it will fit. Id recommend checkin the autoparts websites for an image/part number, then trying to find a replacement for THAT one on amazon or ebay or whatever other website you can find cause theyre getting tricky to find nowadays
Good job 👍
Does your temp gauge work? 1wire plug under the distributor
It does but I actually had to repair the connector cause it broke a few years back but now it all works fine!👍
@@projectgoodspeedwhere did you get the connector at?
@bappolappo3344 I picked it up from the junkyard, and soddered it onto my civic!
any idea why my d16z6 turbo misfire on idle and does not when driving?
@miziaa ohh mann yeahh idk anything when it comes to turbo stuff my civics not that cool🥲
Have you gotten a tune?
I have a vacuum leak I couldn't find. The idol was bouncing up and down, it was a rubber seal in between the brake master cylinder and the brake vacuum booster. When I press my brakes hard it idles fine, and when I take my foot off it bounces.
you know what im gonna check that on mine
Where did you buy your all aluminum radiator and fan?
@30kendel Mishimoto.com
So i have a 97 civic with a 1.6l like to idke at about 1,000 and my idle is fine but when I idle up and let off the gas it seems to drop really fast instead of slowly idleing down almost like a miss but doesn't have a miss in it any suggestion what this might be or is it just a honda thing this is my first honda please let me know
@risingsungarage3508 Sorry i havent got any ideas.. i mean if you idle up its supposed to drop down but idk i guess, what do you mean by ‘drop really fast’…?😅maybe its normal🤷♂️ wish i knew more about car stuff to help you out, sorry.
i have the same issue with my 2007 civic fa1 since i've cleaned the throttle body, did the relearn process with no luck, scanned the car and tried reset the idle but still didnt work, any help ???
@djredx2462 Sorry idk too much bout that year of civics…
Same problem ,,my car at the morning the ildel crazy to,,but after 10 minutes,,,my car running normal back😂😂
Drill a small pin hole in the casting where the broken bolt is and it will come out.
@daveerin3518 yeahhh I tried that with several different drill bits😅 and extractor drill bits… for 2 hours😅
I failed..😂 and the bits broke off
I got a new used thottle body with all the sensors and the fast idle valve because the screws on the old one are both broken. The new one has the high idle prob too so I have to remove the two screws again but this time without breaking them. And in this video I can see that you just drilled them out by hand. Is it that easy? Maybe I try this on the old fast idle valve before I destroy the new one...
@Naru1987 On mine, the head of the bolt just snapped off… what i did is i drilled a smaller radius hole with my drill then i just let a self tapping screw drill out the rest as i tightened it in place. It wasnt too hard but it took awhile since its all i had to work with… yeahh id try it on the other one just incase or just soak the nee one in pb blaster to help remove them… Best of Luck!!👍
@@projectgoodspeed it worked! Both screws were easy to remove! Thank god. The thermo valve is way to wide open, I'll clean it now and put it back together a bit more tightened. I'll try to drill the old one out as you did and put it aside.
@Naru1987 Sweet!!! Yeah i just replaced mine with an OEM junkyarde one in my latest video too!!!!👍 I also set my old one aside as well!!😅
@@projectgoodspeed The idle surge is back :D PCV valve is pretty done too so could be a reason why it is surging. I ordered a new one and I'll check everything again tomorrow to see if I have any vac leaks after I put everything together as I cleaned the fast idle valve. I hope I can find the error because I'm working on my ef6 for about 3 weeks and it bothers me a lot >.
@Naru1987 Daaaamn..😅 in that video i replaced vacuum lines, TB gasket, and tightened the Fast idle Valve. The only thing i didnt do is touch the IACV because its super expensive for me sooo hopefully its not your either…😅 i did actually have some issues with my PCV valve shortly after fixing my surge issue soo it COULD just be that aswell but all i did is clean it. Maybe ill do another video on that as well… 👍
EGR?
Does it affect anything running it with a poor idle ?
@caballero_nunez738 I mean.... it will still run hahah I ran it with a poor idle for 9+ years haha
did you ever fix that sloppy shifter
Yeahh i posted a video on it a few weeks ago..👍
Can you tell me where the vaccum pipe at 6:07 is coming from because mine is disconnected please?
@powerbuffboy9510 Sure! I just checked and it seems that hose is a vacuum line that leads to the charcoal canister. Its located up against the engine bay under the fuel filter. It has like 2 or 3 hoses connected but the hose from the throttle body goes on the cap. (The BOTTOM port NOT the TOP one). 👍 hope that helps!
Ive checl and clean my tb my iacv and tps but i still got idle issies i even changed pcv valve and tubin but it idles weird still
Did you check the fast idle? You know i read that with these types of valves (iacv & fast idke) sometimes cleaning them just isnt enough. You might have to replace them. If i were you id start cheaper tho just to be safe. Maybe try doing a coolant flush and then checking your vacuum lines but tbh i dont have much experience. I mean.. I barely fixed my idle issue and ive had this car like this for years…😅
What year your honda? 98 honda don't have fast idle valve.
@Bitcoin_Gold its a 1995
@@projectgoodspeedoh ok.. my 98 honda rpm drops so low when engine is hot to 200 rpm when ever I make a stop and it's about to stall I have to rev it keep it from almost stall. The rpm never goes low when weather is cold.
I changed my iacv 4yrs ago and just changed part plugs 3 days ago, pcv valve 3yrs ago. Never changed TPS sensor. What could be causing it
@Bitcoin_Gold Damn…Thats a tricky one! Well im no Mechanic but i do have a couple suggestions.
Off rip you could try adjusting the idle speed screw on your throttle body (steps/specs are online for your engine).
I know sometimes the fuel filter could cause similar problems but ive never experienced this.
Also i would try checking/replacing the cap and rotor on the distributor. If you see corrosion or white build up on connection points. Sometimes the cap wears down the connection points that the rotor cant make enough contact.
@@projectgoodspeed ok thanks for suggestions.
very dangerous surge when at a stop, 95 del sol. My mechanic got everything done but surge. so far $2000. Afraid to drive with surge. I am so unmechanical, Honda dealer next move $$$ Idle surge repair,roof leak repair, and stereo repair, o yea floor mats. I am guessing $3000, does that sound right. Car in excellent condition, a few more repairs and watch out SOFLO! LOL!!!
@donaldcassidy1592 WOW!!!! $3k?? Thats a lot but if you dont feel comfortable working on it yourself by all means let the professionals handle it. 👍…..but 3k seems a bit high to me. Dealers be taxin!!!
I have the same problem, will it help Broer
My civic basically had all the possible problems that lead to the idle surge issue BUT i still drove it like that😅… after i addresed them tho, it definitely went away and has not returned 👍
👍
Did you get a P0505 code?
Same here man, keep getting P0505 code. Cleaned throttle body, replaced IACV sensor, and every once a while it'll surge again. P05055 keeps happening ,but gotta check thee hoses now
@easyvwj597 sorry guys, thats beyond my expertise.. i didn’t get any check engine code… wish i could help but i know probably as much as yall do😅
I get the same surge when i drive at 40 mph i have a 09 honda civic
@dd___dc yeah that sounds like a different issue idk too much about that Gen. Civics
Has anyone notice their car overheating cause of this?
Yep mine would slowly over heat especially when idling as the intake itself would get hot due to the surging.
@@jovo21Mine heats up if I drive it, if i have it just idiling so far it hasnt overheated on me but im sure eventually it would, but I notice the lil white piece in the FIAV gives a lot of resistance to the point where I need to force it in or out and everyone just simply twists it with their fingers, Ive decided to fully switch the throttle body since it was from a junkyard anyway and imma see how it goes from there, i also just found out that apparently I have to reset the throttle body or sensor or some shit once putting in a new one.
@jovi21 yeahh im not really sure about any overheating issues… i know that valve i cleaned is coolant related and ALSO has an important piece on the other end i never touched which can go bad. And yeah youre supposed to “tune” or “reset” the throttle speed and there is a specific step-wise order to do this but i havent done it on mine either. Lol but it runs thoo😅
@@ikzuqany update on your situation?
Bro how it feels that i got mine a 93 coupe civic and after driving it for long it loose too much Power like trying to shut off if driving slow that's a symptom? Never saw my gauge getting high or some
It was the fast idle valve, once you screwed the valve all the way down it corrected the issue
Hey can anyone help me I have a 1993 Honda civic and coupe EK It’s fine untel it gets warmed up and then it studders but if you shut it off it’s fine i think it’s ecu and timing and It runs really good untel it gets warmed up and then it studders if you shut it off it’s fine tho for a little bit but this video makes me think this guy is right but can you guys help me anyone creator or commentators ?
@Chrisorozco123 Ayyye man im no mechanic…. BUT….lol ecu and timing issues gunna be expensive to diagnose AND fix. Try adjusting the fast idle like i did and see what that does, i mean if it does nothing all it costs you is a jug of antifreeze but an ecu or timing issue gunna cost atleast $200…. Worth a shot id say🤷♂️
@@projectgoodspeedI’m going to take your word and try it out bro
@Chrisorozco123 👍 gotta start with the cheap solutions first before you go and spend a couple hundred on ecu and timing stuff… the civics have 2 valve responsible for the throttle both have coolant running through them but hopefully its as simple as adjusting the Fast idle valve because the other IAC valve is dummy expensive lol
My 1972 Datsun 510 never does this,i guess ford 5.0 engines don't surge.
I Can See An Amateur On Hondas On Easy Fixes Like This
Put a k in it
I wouldnt mind a K series… But California has really strict smog regulations😔 id have to find someway to make it legal and i havent seen anyone do a legal K swap yet😅
It’s just a aggressive cam
