I have a h22 swapped in an integra. The swap was done cleanly and the right way but anyways, When im driving and then come to a stop, the motor keeps revving from 1k to 2.5k RPM repeatedly and eventually will stop after 3-10 revs. At first it used to do it only when you would drive a few feet in traffic and when u put it in neutral the car would rev up about 1k RPM higher and then go back down to idle. It doesnt do it when I first start the car. And I adjusted the TPS thinking it wasnt set correctly because the two screws were loose and I set it to .49V and now it Revvs by itself more often now. I dont know if having a blox throttle body affects anything. And I have a stock p28 unchipped/untuned yet. IDK if those two things will affect that.

Bump.....

what ecu are you using?

chrisff521

I think its a stock p28.

chrisff521

It's actually a chipped p28 and now I'm thinking its a vacuum leak because it idles high and revs from 1k to 2.5k still.

chrisff521

Is it possible to find a vacuum leak the same way we find boost leaks with the boost leak tester. pressurize through the throttle body and then listen for leaks?

What does it mean if my car only starts idling like that when the car warms up. When its cold it doesnt do it.

I have the same problem and I think it's air in the cooling system. I had to pull a coolant line and mine has had the same idle issue as yours since then. I've bled it a few times but I know I haven't gotten all the air out yet.
