2000 Z28 just started getting a random cyl. misfire at idle, only when in park(P). If someone could point me in the right direction much appreciation.

Is it thoughing any codes?

Yeah you should see a CEL for that. However even if you dont see one try and get the car to advance auto parts. They have a code reader you can use. some times the car will throw codes and not show a light right away. That is what happened to me in my contour.

No CEL. My scanner at work didn't find any codes.
