It does not work on every IACV on all cars. But these seem to be very basic ones. Started to get a rough stumble at start up then the fast idle valve takes over and then warms up drops down and runs fine. It is the IACV. They get carboned up over time and can cause these symptoms. You must use a carb cleaner that will not harm 02 sensors ( Because of the probe inside the IACV operates the same way). So has anyone tried it on these with success?

That part isn't the IACV from our cars is it? It doesn't look like it, or as I remember it anyway. What I DO remember is what it took to connect the coolant hose from the valve to under the intake manifold. I couldn't do it, and my mechanic said he used up his daily ration of cuss words on the job.
That is the back view that mates to the manifold. So you can see the plunger inside. I just am curious if anyone has done it on here. Here is the front view that should look more familiar.Originally Posted by w261w261

Yeah, you have to clean the coolant chamber on the bottom as well.

You have done it and had good results?

Maybe this is something I should consider, but I guess I'll wait until I have an issue. I just replaced the two little coolant hoses. OTOH, it looks like it comes off easily, so maybe a candidate for preventative maintenance.
I've had zero idle problems in the 8 years and 140k miles I've had the car. Maybe I'm fortunate?
Yes, it helped.

I imagine the gaskets are available from Honda?
Gaskets were not completely bad, I just added some gasket sealant Blue RTV sensor safe.

i had a stubling idle once... the iacv was completely blocked and full of carbon... swapped it out for a used one (in better condition) and it worked fine... but as far as cleaning goes... i just used soap and water and it works fine even for the water jackets on the bottom.. be sure not to get the electrical wet or youll have problems til the part dries

I have a weird idling issue when it starts up... the RPM's bounce up and down for a while, then smooth out. Would this be a cause for that?
Where the heck is that at on the motor?

^^if your car is an 87 it may not even have one iacv is 88-89 only but you will have a fast idle valve which will be causing the rev bouncing its on the back of the intake manifold with a cap and 2 screws holding it on.
Didn't know that. I will have to see if I can find that...

Cleaning it did not work for me. It will either rarely work or get worse on a 22 year old part.My got worse ( barely idled after cleaning and drying for days) So since I did alot of work on the car the past few days, I decided to splurge and get a brand spankin' new one. I tell you it is a beautiful thing. No minor stumble at start up and idles as the day it was born. It was worth it to me.

Where is this valve located im gettin a code 14 for some reason today
middle of the intake manifold. Has a 3 ? pin connector and 2 coolant lines hooked to it. I have had to loosen the lines and get air out there that the bleeder would not.

That's a great idea. I have resorted to jacking up the front of the car, but I'm still getting some idle bounce when cold.

the cold start issue might be the thermovalve on the manifold... i blocked that one off and the iacv and it was good... cold starts were a bit low on the rpm scale but when it warmed up it idled like a champ

that picture is not the valve for our accords thats probabaly off a civic and yes if you clean it out it helps.
and if your revs are bouncing its because the thing on the inside got loose and all you have to do is tighten her back up and clean the inside and your problem should go away.
and its located right next to the throttle body on back of the intake 3 bolts hold it on and two coolent hoses on the bottom.
Danny that is it bro .....It only on a 88-89 .home slice..
And thanks for the bleeding idea. Ol BlUE YOUR THE MAN
WOOOOOWWWW!!!!! i cant believe i forgot about the dual air flow intakes haha
sorry guys i forgot.
I cleaned mine out with a set of dental picks and sensor safe FI cleaner. Took an hour or so. I filled my IACV up though with FI cleaner to the brim and let it sit until it evaporated and it made it like 100X easier to scrape it all clean. Just be very gentle with the pick. And save yourself like 2$ from honda and O'Reilly's has a perfect fit oring for 42cent(When i bought it a year ago)
