Hi folks, I really want to get this problem fixed as it is getting really beeping annoying. Please don't tell me to bring it to the dealer, they are useless and stupid. Anyway, the problem I have regards my idle. Basically I have a late 04 with 15K miles on it, the car had never idled perfect with the AC off. I tried adding ground kit and cleaned the AFM just now, but the car still doesnt idle with the AC off. It would jump up and down varying by i would say 50-150RPM at idle. You can clearly see the needle bouncing. Other than the annoying factor, the car does work good. I removed the intake tube, everything seems to be nice and clean. I will try to test for vacuum leak by adding a vacuum gauge and spray carb cleaner later, but what else do you guys think i can do? The car shows no check engine light and everything works good.
