My first ever post here (my real car is an '88 Monte Carlo SS) and I'll do a search right after this, but,

I need help with a problem on a girl's beater '97 with the 2.0dohc.

The thing sputters at low revs hot and cold, trouble starting cold. Runs better if not nailed to the floor.

Plugs are fine, wires give great shocks when pulled off while idling, found one vacuum leak and no more.

EGR code 2 months back, but not since. Wassup?

 

Bunch of electronics bad? could be, but probably not. Like the SS though... Thats a car. but dont tell my car that; she might get jealous, cause thats who she replaced.

something wrong with the egr? did you fix it? Id be checking all the vacum lines. is it the 4g63 turbo or 420A motor?
