so my car was running perfectly fine. 91 b16a hatch, and than at work today i decided to get the intake cleaner for your throttle body n etc. and well since my tb was black inside me and my manger went and did what the can said to do as well he has done it before. well it cleaned up my throttle response as in no more hesitation but now it idles all high, at first it was going from 7-1200rpm and than after a while of driving it stays at around 1200-1300rpms. =/ why is it doing this for? oh and i tried to turn down the idle screw but it was already down to the lowest setting

 

could be the air intake cleaner has clean the dirt and gotten into ur IAC

 

so just clean it out and it should be ok? ima try do that now. thanks for ur input other ppl too?

 

drive it on hwy for a while should clear up
