@nelsontorres2900 Thank you!
As a diy guy with some experience working on cars, I want to say your knowledge and the way you take time to explain things are very informative. I'm slowly educating myself on obd2 systems and your information is very helpful. I really like that you show a step by step process. Keep up the great work.
@billwhite5853 Thank you!
Another problem with older Hondas with iac valves. There is an additional valve that lets in air to aid in fast idle with a cold engine. It is a wax pellet valve that reacts to coolant temp. It is open when cold to allow additional air into the intake to increase idle speed and as the coolant heats up the valve closes and shuts off the air. If the coolant level is low the valve won't heat up and the idle won't come down. When the engine warms up the computer sees a high idle with a closed throttle and it goes into fuel cut mode. That causes the surging. Often the only problem is low coolant level.
@OzFrog48Z Thank you for sharing this with us, I appreciate it!
Happens alot on the gsr/ls engines and d16.
@@KITS_Auto_and_Truck_Repairclean all the ground bolts and wiring harnesses with isopropyl alcohol and blow them dry with an air compressor and reinstall the next day. Including computer ground bolts and harnesses inside the car. It takes a few hours, at the end of the day - to be certain all the alcohol has dried.
You didn't say the model year on the car, or your geographic location. So they salt the roads?
As the top comment posted. This was a known issue back in the day with a bad Fast Idle Thermal (FIT) valve. Air in the cooling system would give you the same surging idle. Air can enter due to a leak somewhere in the cooling system. I had a leak at the inlet hose to the FIT valve in the past, so that was where the coolant would escape and air would take it's place. The location of the valve was the highest location of any coolant passage, so the leak was slow to appear under normal conditions. I noticed the coolant a bit low and pressure tested to find the leak.
There is always a reason, the "Amazon" sensors/parts are a small fraction of the cost, compared to OEM!! Especially HONDA or ACURA.
Always go oem sensors or electronics, for Honda.,...Always. HONDA OEM,...always solves the issue.
Very nice explanation,I did work for Honda dealer in Texas (just water sprite to detect vacuum leaks)if you have the insufficient code after a new EGR is a EGR port down thev intake collapse of slosh you have to clean it and install a bronce pipe to avoid the problem again (it a O.E kit to do that problem)hope this information helps some body

Nice work! Wish this video was available a few years ago. I had this issue with a 2000 Civic Si and I sold it because I didn't have this knowledge to resolve it after several local shops were not able to fix it. I kept throwing IAC valves at it and the issue would come back repeatedly after the motor was HOT.

Sorry @michaelkelly3501 as my previous post implies I sold the car (unfixed).

First time viewer, 30+ years in the automotive trade. I gave you a thumbs up and a sub, so now I will be looking for you to impress me, lol. I would not have put the aftermarket EGR on this car, especially considering what you said. If you are going to tell the customer that they will probably need an OEM valve in the future because the new one has a slight leak, I would just leave the old one on which also has a small leak. But I would tell the customer that they are going to need a new OEM valve now or in the very near future if they want there vehicle running right. Just my opinion, other than that it was a good video. You two seem to have a good synergy together, keep it up!
@mikeburdi3464 Thank you! and welcome to our CZcams community!!
He had EGR flow codes with the OG EGR valve.
Nice job guys. I have always used starter fluid to find vacuum leaks quickly. This is the first time I have seen a smoke machine used to find leaks. But I do not work on cars as a professional. I have rebuilt several engines in my time though.
You have to use starter fluid while the engine is cold of course and use it sparingly and only spray at intake components. Stay away wires, connectors, or near the exhaust. Starter fluid near heat and/or an electrical short/spark can be dangerous.

EGR sticking open would cause rough idle, stall and fuel trim correction towards negative in a MAP system.
On these it's usually low coolant, vacuum leak or I've also seen where someone messes with cable adjustments.
Lots of good comments in here also btw.
@JimmyMakingitwork Thank you for your input!
Bishop correct you are the man sirs greath pepole thank you.,.😊
I believe you answered my question that I wanted asked . With the unmetered air going in the EGR , would it cause the MAF reading go into negative values ?
I use the feul trims data on scan tool when i suspect vaccum leak , high trims at idle drops as u increase throttle . and perhaps stuck open evap purge solnoid
@wagoosh78 Yes!

Other than air and oil filters, I always use OEM parts. I learned my lesson with using reman NAPA rear brake calipers for my Accord. 2 years later I had replaced both calipers a total of 4 times because of junk NAPA reman parts. Sure they're under warranty, but when your brake calipers sieze unannounced and it's -5 degrees in the middle of February, you'll be sorry you went the cheap route.
@milfordcivic6755 I agree with you!!
I have a question .......Can you explain what happens when you pump the brake pedal to test the 02 sensors? I saw you do it on one of your older videos. Just thought that you might see my question on this recent video as you reviewed the comments. Your skill is self evident and your gift in explaining what you are doing and why is such a wonderful contribution to all of us DIYers. Thank you for that! God Bless you.
@ronniestevens9268 My Pleasure! when You pump the brake pedal while the engine is idling you create a lean condition on a vehicle that has a vacuum operatedbrake booster, because in the booster there is vacuum on one side and atmospheric pressure on the other, so pumping the brake pedal allows air to enter the vacuum chamber and create a lean condition, since the vacuum side is attached to the intake manifold, when this happens 02 sensors that are good react to the mixture change very fast, indicating good 02 sensors!!
@@KITS_Auto_and_Truck_Repair I understand. Thank you for explaining that. That is very helpful and a valuable bit of advice!
@@ronniestevens9268 My Pleasure!
Not certain of this car, but I have seen egr system issues [specifically a modulator] show up as poor milage/long term fuel trim staying high. The loss of control [a broken diaphragm] was a vacuum leak, but since egr readback was proved by temperature sensor it threw a low "flow" code. Worked I guess, but the language choices used sometimes lead us down paths that eat up time. Egr's are odd ducks: active for moderate acceleration, but off under something like 1500 rpm. So I wondered about the surging: a return to normal [intermittantly] but most the time system is compensating using IAC to keep it running? Again, fuel trim is often a good clue. The funny thing about egr codes [if that is what set this trouble up in the first place] is that replacing egr may well be the last thing to do - you said "aftermarket" regarding egr and that right there is a red flag. Your smoke machine got it done - that can be a great timesaver.
@flinch622 Thank you for the input I appreciate!
Wouldn't the O2 sensor reading be on the lean side as well for constant unmetered air entering through the EGRV?
@@rambleon2838 fuel trim corrects that and mileage goes south. In some ways, the O2 sensor referees most intake side malfunctions because it has the final word... which is why fixing certain exhaust leaks is important
Awesome stuff! You are the man!

I had this same issue on my saturn wagon. 1.9 twin cam. Replaced everything ya'll did, and more, smoked it with no leaks, even replaced plastic valve cover with the aluminum one. Ac switch, ign sw., map, maf, intake temp, coolant temp sensor, throttle position, throttle body with relearn, brake booster and check valve, and vacuum line to intake, checked intake gasket with water, brake clean, oil, and fuel to no avail. Replaced ecu, and even the power steering pressure switch. Nothing fixed it. Drove it for a few months and trashed it. I gave up and just dealt with it. Scrapped it for 700
@mikeschaner5853 Oh dang I'm sorry to hear that you had to get rid of your car for this issue!
@KITS_Auto_and_Truck_Repair i drive 60k + per year delivering meds. I replace the workhorse every 10-14 months. Tbh, the only reason I scrapped it, was because the yard offered more to crush it, than my highest offer privately for 2 months 😆 🤣..1 guy came to purchase for 8, knowing it had this high idle, and knowing it went thru a quart of oil every 1500 miles, and got mad at me when it smoked with a high idle lol.. I found myself an 03 sentra ser spec v, 2.5L 6 spd for dirt and have been fixing it up slowly. Shouldve honestly filmed the process.. good show guys. Looking forward to seeing more of your content.
I have replace the iacv for a new denso one, replaced map sensor, purge valve, tps and also replaced the injectors and manifold gasket but still have the code p0505 and car jerks, high rpm idle and surging idle, rpms get stuck and then jump to higher number, i need your help please i have a 2002 honda civic si hatchback, i dont know what to do

Not sure if it was mentioned, but I would've monitored the scoping of the idle valve at operating temperature to see the valve open and close. I'm assuming there would be some distortion in the signal when it's commanded to close
@user-sv2ex7ux4i yes!

@maxnguyen22 Yes!!
Will the leaking EGR valve introduce exhaust gases into the environment of the nearby AFR sensor and disrupt its accuracy?
@jptrainor the leak was not big enough!
Good video, Thanks for Sharing! I'm curious to know what the fuel trims were, with the bad IAC.
@advancedleveldiagnostics Thanks!! I didn't look at trim numbers, I should have, I'm pretty sure they would be in the high positives
That is kinda what I was thinking of looking at o2 signals. ALD peace gtsy I just subbed this brother technician he is very analytical I like his diagnostic approach like yours ❤😂
always look at fuel trims when diagnosing.
always check the obvious first, would have saved you alit of time but great vidio guys
@scottandpamelairwin1987 Thanks!
There was a recall on the EGR valve for these engines years ago. Is the "old" one a replaced EGR valve under the recall or is it the original defective design?
@Aberdeenroadie We replaced the old one with an OEM one!
EGR needs a TAP TEST to see if it is sticking. If the IACV (older models) has some coolant lines going to the TB, which is not fully warming up the IACV due to air or junk trapped in the coolant area, this can be one problem. Since the IACV does not properly close from not being properly heated up, it acts as a vacuum leak, air bypass leak around the butterfly valve. I now see you have an EGR leak which in some cases is a built-in vent hole since it's on the top area away from the EGR plunger check valve face, the top should only be the position sensor and solenoid electronics.
Honda likes to open the IACV off idle so when you are driving and come to a sudden stop, the IACV is not closed and the sudden closing of the butterfly valve does not cause the engine to stall and allow the IACV to close off slower at stops. An old test is to watch the Duty Cycle at a stop, fully warm, in gear, brake on, then release the brake and allow the car to roll and watch the DC as the PCM now has a VSS signal that can tell the IACV to open a bit so when you stop, the engine will not die from a sudden stop of the VSS. YES YES YES, plugging the port, inlet bypass port to the IACV is a proper test.
You may have experienced a bad ICV in a Nissan that is electronically heated and it also does not fully close when hot so there is an idle problem also, the same scenario here in my story. Clamp off the air hose going to it and problem found, no more bypass air leak. In other engines, the TB Gasket can be put backward blocking off a bleed port causing problems as the bolt pattern is the same both ways but the port holes are not.
If you had a sensor simulator handheld tool you could create your own PWM, (name ?). When you do tests, I wish guys would show final good test results, this was prior to the last IACV, SCAN DATA MAP 0.9V Idle IACV 1.0V At 1400RPM, if you don't mind, please redo verification testing for the YT viewers. Thank you for the case study as always.

Good video. I have one question.
I got a car (manual) that shifts gears hard when the car is cold, and whenever the car runs for a bit then the gear starts to shift more easier...What do you think it can be? Oil change? Intermittent issue. Thank you very much man!
That's odd! you could have a sticking clutch disc! etc...
Hello nice tutorial
Could you have manually operated the EFR ? Most times carbon deposits obstruct it from working properly.
@josephpuchel6497 Thanks!
in my experience is most egr valves will leak smoke especially, ford . also when that surging idle happens tap on the valve and usually it will clear out and work. telltale sign for iac sticking. also focusing on map which will show air leak issue,but understanding that a leak thats to large could be by the bypass of air by the iac, which is a leak if the valve is sticking open to much . also they say that with like a 4.0 your maf should read close to the same, well i watch that more closely on every car thats running fine and i see now thats not very true either ,so i dont just condemn the maf based on that especially on ford. so watch more good running cars and watch the maf you will be amazed how its not like most utube guys say it should be, just delt with one of those hondas a couple weeks ago same issue also cleaned throttle plate and and made sure the tps voltage was correct at idle
@user-te3pn4pb4u Yes! Thanks for your input!
My ford has high miles and throttle plate was sticking closed, hard to get loose after sitting overnight. I cleaned it up, lot of gunk, then idle was too high. Idle screw is immovable so after going through every last other thing to make idle fast - vacuum leaks etc. - I got out a file and filed the idle stop screw.
It turned out the throttle plate passed too much air after cleaning off the gunk.
Far as aftermarket stuff goes, not all of it is created equal. You're likely to get burned using no-name garbage from Amazon or eBay but there are others that are OEM quality, such as Denso, NTK, Hitachi, Delphi, and Aisin, and in fact many actual OEM parts come from these companies. If the OEM part is unavailable or prohibitively expensive, you can usually find an OEM equivalent part from these brands for much less on RockAuto.
@notsureigaf That's some what true!

I am wondering if a scan tool is saying a idle air control valve is bad on a 2003 Honda Odyssey 3.5 v6, but then you clear the code and turn off the engine light and it runs fine for awhile then it acts up again does that mean the part is bad or is it something else? I know this is a different vehicle and engine you are working on, but it seems to me like as a old mechanic if my part is bad I couldn't just clear it even temporarily, Right? I bought a new after market part but haven't put it on yet. Please let me know? I am disabled and only have one vehicle, live in the country and can't afford to put it in the shop.

Hey bud, I remember you told me P219A is possibly injectors.
I have this P219A code on my 2013 Chevy Silverado and I have already changed spark plugs, spark plug wires, all eight fuel injectors, both upstream oxygen sensors, purge valve, cleaned mass air flow sensor, changed air filter, changed dirty air pcv hose, cleaned throttle body and performed idle reset using scan tool.
What else could it be lol?
@TurnThemWheels I recommend you take it to a pro mechanic who can diagnose it properly!!
Its a honda with a map sensor, what you can do next time is to remove the intake, watch the scan tool, and see when the iac reads 0 meaning that its closed, put your finger where the iac bypass and feel if your feeling vacuum, if its says 0 and you feel vacuum, that means the iac isn't moving because 0 should give you no vaccun through the iac bypass

Ok, the EGR functions at part throttle cruise.
A vacuum leak atvthe EGR valve could be eliminated by blocking off the EGR port with a biz card betwwen the EGR valve and the port.
The surging is most likely the vacuum leak at the EGR valve causing the elevated idle indicated by the elevated idle MAP voltage. At idle, N.O.T., the PCM will attempt to bringle the idle speed down using fuel cut.
A quick IAC valve function test at idle is to block of the port in front of the throttle plate and see if the idle speed drops down to idle.
In this cae, I doubt it would have dropped because of the vacuum leak at the EGR valve.
