need help my car idles from 100o rpm to 2500 continuously. some told me that it was the icm valve? if anyone knows what the problem is or can help please do so.

 

yeah you have a vacuum leak...

here's what i did
it's the IAC valve right below my TB on my intake manifold. its real ghetto but a better solution is probably around the corner...

I cut out a piece ov vinyl rubber material i had laying around from some bag or something, you just need somethign that wont leak

then remove your IAC and put this piece across the three holes, then bolt back up.
shoudl do the trick, mine used to crazy idle as well..

 

 

 

check all your vacuum lines running to the intake manifold. you probably just missed one.

 

i don teven have a breathe rline going from my valve cover to my intake tube, a few honkeys at a gas station said that was the problem but then i fixed it my way, and its still fine with ojut one
