all the lights come on when the ignition is switched to on and the they go out after car is started, while the car was idling I took off the plastic shroud and sprayed all around the intake area and vacuum lines with wd-40 I heard no change in the engines idle speed. At this point I am lead to believe that it could be a map sensor, a tpc sensor, possibly a o2 sensor, hell maybe even a fuel injector. What has me baffled is that my ses light hasn't came on at all, and I know it works. Thus Frustrated!!! lol guess I am going to have to break down and take it to a GM dealer, my wallet aint going to like that!
