Here are my symptoms.....

[VTHokieDoc]

When my Cobra is idling it bouces back between 1200 and 800 rpms and eventually comes down to 800 rps after 1 minute, the air conditions blows only luke warm air, and my temperature gauge doesn't move a mm off Cold when I am driveing it in 95 degree heat. Besides the obvious answer that I have an electrical problems, do any of you engine Dr.'s have any clue whats going on? Thanks again

Sounds like you need to recharge the A/C. If the clutch is cycling on and off it can make the idle jump. But the idle is probably the IAC needing cleaning or changing.

With the gauge thing though it all could be a ground problem.

Check the negitive cable at the battery and also at the block. Tighten it with a wrench at the block, don't just feel it with your hand and say its tight.
