maybe vacuum leak somewhere?

Thanx josh but iv looked all over this car for vac lines and even have haynes manual and cant find one. Manual says comin off throttle body but there is none just break booster


i got a buddy on fb thats a cavalier guru. his names kieth cabral. look him up. he knows things about them most prolly dont. hes got a nice one thats buikt to the gills. you should have vacuum for defrost, egr, booster, cruise. maybe mass air flow sensor. find it and give it a couple light taps w a screw driver whule car is running. it should change the way it runs if its good. if not then its bad.

Im not on fb bud but ill sure try track em down. Iv built big blocks for years this lil 2.2 wont defeat me... Lol thanx again
