Hey guys just trying to sort out some minor stuff on my girlfriends cavalier, it's throwing 3 codes, one for high idle and 2 for evap codes, is there an adjustment for the high idle somewhere on the car, or is it all done by computer, and if it's done by the comp, can i run through a carb cleaner, inj cleaner, and carbon cleaner, some info on the motor, it's the 2.2 auto
Nope, high idle ususally indicates vacuum leak on these cars. There is no adjustment. As for the evap codes, get it smoke tested, otherwise you'll throw near $1k in parts chasing it down.

The high Idle and evap problem most likely are connected. Check the vac lines on the purge valve on the back of the engine block.
