For those who read my previous post "bouncing idle" I resolved. Turned out the air sensor was not well connected! However, now there is a smaller problem. Whe the car is ither on "p" or "n" the car idles fine (with a/c on or off), however, when the car is on "d" or "2" "r" etc, the car idles terribly. It seems the idle drops and wants to turn off. Any suggestions? Thanks in advance.
