You can clean the passages on the IAC with carbon cleaner.

If there is irregular idle such as fluctuations or slow reduction, it can be caused by a sticking valve. For this, you can take the IAC apart and clean thoroughly clean the internals and then lubricate. For example, I had an Accord with rev hang when the engine was cold and it was because the valve was sticking during rotation. A simple cleaning and the vehicle idled perfectly.

There is an air bleeder valve on the top of thermostat housing on most Hondas. Warm it up to build pressure then just crack enough to see it bubble air and coolant. When it flows without air shut it off and spray off with water or brake clean. Sometimes do as a maintenance, as air can collect there over time.

You can ues brake parts clean and the iac valve will be good as new, too.

I have a different problem on mine, the idle goes very high (2-3k) under some conditions, usually re-starting a partly-cooled engine or when steering down my driveway in neutral (it's a manual). Looks like this is the area to check for problems. Thanks for the video.

When you’re doing the finger method, sorry I’m dumb, what air is going through? Are you like running compressor air through it some how? Or is like the car just to the on position? I’m just wondering where your airs coming from I need it spelled out, great vid btw I’m working on my 05

I just installed a brand new IAC valve but not my idle rev is ~1400 and then it tends to fluctuate (revs up and down) while idling.
Any idea what’s causing this? I did let it rev at 3000 rpms and let it get to 196 degrees and then I let idle for 5 minutes. Any help.

@jonwillfixit I had the same issue. already tried cleaning, replaced it 3 times, aftermarket and junkyard. how can I check the wires, I understand that there is 12v power, ground, and then signal. How is the signal wire supposed to look like in terms of volts? Where can I find this information? It sucks that you were unable to record that process.

Thanx for this video! May you and your family believe in Jesus Christ and be saved!!

When you take it for the test drive, I suggest putting a little gasoline in the tank. You can always charge the customer, and it beats having an empty car clogging a bay!

[addieisaacs]

I really like how you took ownership to a problem you cld if possibly caused and didn’t try n tell customer there was something additional they had to pay for. #honestMechanic

** I might add why didn’t you just clean the IAC instead of replacing it?

[AlfredoCrazyFreddyRivera]

Why didn't show the actual part... that you replaced... Whats the actual part model if you don't mind sharing that and name boss... appreciate it

[cthecoalman]

hey just giving you my problems so at a stop the car wants to almost stall but doesn't and no change in the rpm at idle to make a big difference gas consumption has increased so tomorrow morning going to pull the iac and clean the throttle and replace the iac and see if this fixes it I will let you know the results

[josevega]

So if it stalls then the iacv is good when doing the finger method And if doesnt stall and idles correctly the iacv is bad ?
