So my car has been having a random stumble in idle. I watched a video showing someone cleaning an iacv. I cleaned it with brake clean. I also cleaned the throtle body as well as all of the holes that are in the tb for the map sendor ect.Start her up and i all of a sudden get the iacv idle that sounds like i have 272 cams in it and idles high( nO tach but sounds like 1500rpm) i just got a cel so i will report back with what it was.

 

check the vacuum hoses, I knocked mine off the back of the intake mani when I cleaned my iacv and it drove me crazy for two days trying to figure out what was wrong. I even bought a new iacv just to find out it was a vacuum line.

there should be a diagram off all the vacuum lines under your hood.

hope its just a vacuum line. GL

 

I just cleared the code, it was a IACV code, then I also went the extra mile to unhook the battery
.I went back in and re cleaned everything. I also put a very little amount of gasket sealer in there. I hunted when I first started but it didn't rev to 1500 again. After about a minute it went away. it was good on my short trip before. We will see how cold start is tomorrow.

 

Ttttt

 

Sometimes you have to let it dry out, just reset the ECU and see how it is for a few days.

When I cleaned my throttle body I had the same problem.
