I just installed the greddy pulley's the otherday, and got rid of my air pump, now when my car fully warms up and drops to 800rpm the idle bobbles around, kinda sounds cool, but I know it shouldn't idle like that. Would I have a vac. leak somewhere? I checked the otherday and didnt see any (i have all new silicone vac. lines) leaks. What would you look for?

 

It's because you removed the air pump.

 

^that's what i was thinking, but wassn't sure. Anybody else have idle like this without the airpump?

 

Your idle should be at 720
When I removed my airpump, my idle stayed at 720.

Lately though, I've noticed a lopey idle when I turn my
parking lights on.
