Does anybody had this happen before or know what causes it?
My 2012 C5 classic idle RPM hunts (goes up and down) and eventually after 1 or 2 minutes shuts off. I can start it again and the problem is gone for a while, but even after riding a hour or so if I stop at a redlight it sometimes tries to stall out again. Took it to the dealer and they could not find anything, so theu just increased the idle RPM.
