Ok heres the problem, I'll be driving my car fine and all, but as soon as it warms up and I stop the car at a light the idle goes from 1000 to 1200 and just bounces there. It never goes back to the 500 rpm it should be at and the wierdst thing is that if it doesn't jump from 1000 to 1200 I can pump the break and that will make it raise to 1200. I don't know what to do. I looked around through some other posts and I think its my idle air control valve but I'm not too sure.

 

mine went bad... I justed took it off & welded the hole shut

 

Thats funny JDM LUDE!
I spent some time today screwing around w/ IACV's physical and duty cycle components at work.. They prolly cause more headaches than anything else and I guess plugging the hole ain't gonna hurt anything.
