I have replaced a number of sensors on the car but need to run it through the cycle as the battery was discounted for replacement of the Bose head unit and the CDM along with recent replacement of the MAP, ATS and TPS.

I'm not sure how different a C4 would be as my '85 doesn't get an emissions test.

You might want to post this question over on the C4 Tech Forum if you need a more detailed answer.

Oh, and welcome to the Corvette Forum...

Good luck... GUSTO

The old OBDI systems don't have a drive cycle since there are no emissions monitors.
