This past winter my camaro started giving me trouble when I first start it up and now whenever it runs in open loop. As soon as I touch the clutch the engine begins to fluctuate RPMs ranging between 400 and 1000 RPM and will sometimes die. Once the car is warmed up it runs great. I think this has something to do with the clutch anticipation switch.

I have already replaced the computer and temp sensor and sending unit. I have also flashed the computer a couple times to see if it makes a difference. No luck so far.

Any help or suggestions on this are greatly appreciated, as my local garage is baffled.
