well i started messing with a few things and now it revs from 1000 RPM to 1500 RPM and back. i took my hand and placed it over the throttle body intake and it killed the motor. someone told me that that was a good way to check for a vacuum leak. i also use smoke from my cigarette to check for leaks in the vacuum lines. ok so now i have no leaks, so i check that thing that bolts to the back of the intake manifold, i think its called the ivac or something. when i unplugged it, it instantly started idling smoothly. now my check engine light is on. so i am guessing that it needs to be plugged in. does any know if cleaning the ivac would help or if i should just replace it.
