I am having ithe same problem with my car right now. I went to auto zone and was throwing two major codes that could cause this, MAF and for the 02s. I will be watching closely.

Okie02

isnt there some kinda idle relearn deal i could try?

You have a cam for it right. I had my idle reset twice, and still doing the same thing. Is your SES light on?

I did not have my 02s at first, had the car retuned, and went back to what its doing. I am thinking MAF at the moment being the problem.

Okie02,
This is the procedure for the Vette. Not sure if it is the same for your car.

From the 2001 Service Manual:

Idle Learn Procedure

The learned idle procedure needs to be done if any of the following events occur:

- The powertrain control module (PCM) is disconnected
- The battery is disconnected
- The PCM loses power
- The PCM is reprogrammed

The engine idle is unstable when the learned idle position is lost.

Automatic Transmission
Perform the following procedure in order to return the learned idle to the correct position:

- Turn OFF the ignition.
- Restore the PCM battery feed.
- Turn OFF the A/C controls.
- Set the parking brake, and block the drive wheels.
- Start the engine.
- Ensure that the engine coolant temperature is more than 80°C (176°F).
- Shift the transmission into Drive.
- Allow the engine to idle for 5 minutes.
- Shift the transmission into Park.
- Allow the engine to idle for 5 minutes.
- Turn OFF the engine for 30 seconds.

Manual Transmission
Perform the following procedure in order to return the learned idle to the correct position:

- Turn OFF the ignition.
- Restore the PCM battery feed.
- Turn OFF the A/C controls.
- Set the parking brake, and block the drive wheels.
- Place the transmission in Neutral.
- Start the engine.
- Ensure that the engine coolant temperature is more than 80°C (176°F).
- Allow the engine to idle for 5 minutes.
- Turn OFF the engine for 30 seconds.

I just replaced my engine sensor fuse(it was blown), and runs perfect. Hope this helps you out.
