Oh Great Electrical Guru's
I am feeling a lot of pain with these on going elecrical problem's.
#1 problem is when I start my car the a/c starts as it should. In just a few minutes it turns off never to be seen agian. The system is charged. It is like the computer is forgetting to turn it back on.
# 2 When The car is first started. There seems to be no miss. As the car gets warmer. The miss slowly gets worse between 2500 and 3500 rpms. If you accelerate through the rpms. There is no miss to be felt. Go at a slow or steady pace and you will feel it. If you hold the rpms while driving at above 4000rpms. There is a hint of a miss only.

Check for codes set if you have the electronic climate control. Go through the system diagnosis for compressor controls diagnostic tests found in the electrical diagnosis service manual supplement available from GM.
Miss at high rpm is usually spark related. At night look at your plug wires while revving the engine and also check that your loom guides are all there and in good condition. Plug wires are kept away from ground by the loom because all plug wires have microscopic pinholes and spark will jump to ground through them if ground is close enough.
