Hmmmm...Interesting...

My car has been idling really roughly... once its warmed up, it kept jumping from 1500-2000rpm (about). I did a lot of reading up on the forums throught the SEARCH function that oh so many people dont know about..lol. Anyways, i adjusted the screw on my bac, and the jumping went away.... now it just idles at 2k consistantly. But from what i read, the screw was supposed to raise/lower idle. Now im confused. Does anyone have some info... also, on how to lower my idle now?
thanks

Jumping idle would typically point to a TPS that's either out of spec or bad. Try a new search for setting your TPS (throttle position sensor). Set that, then adjust the idle via the BAC valve.
