Default Idle question
I just got my first C5 today (03 with 22K), and noticed a very slight rough idle. This happens only when idling in drive.

I don't know if these LS1's should be perfectly smooth. It is completely stock for now.

Could be a number of things. On mine it was a worn out serpentine belt. Belt tensioner was bouncing around.

My rough idle was caused by a dirty MAF sensor and throttle body.
