My rpms hang when I come to a stop. Usually with the a/c on but also does it with it off. I did the block off plate mod. Didn't work. New Iac valve. Still hanging. Could a vac leak cause this.....
You are not getting 15mpg becasue of a hanging idle :bash:Mine only hangs when the AC is on and I come to a stop; but my rpms hang at 1800!! Only when the AC is on. Been getting about 15mpg lately because of this stupid issue. And I notice the battery power level goes pretty darn close to the low limit. Sucks doesn't it? Ha.

I have found if you hit the throttle while its doing it and you are at a dead stop it will lower the rpm's where they should be
