sometimes i hear a pop from my exhaust and then my idle drops 300-500rpm. detonation? My idle is set to 1200rpm. if I set it lower and have my headlights and heater blower at max... my idle drops 200-300rpm. Plus when my rpm drops from 3000+ after i lift off the throtltle.. the car drops to 300rpm and sounds like it wants to stall. I need to get a new TPS or something. my car needs to get professionally tuned. :/
