Default Check Engine Light

Every time I turn on my AC, after a few min's the check engine light goes on. Turn the AC off and the light goes off in a min or so.

Any ideas?

This site will help you out a little. Depending on what year you have you will probably need to have it checked with a early model code reader.

1981 Corvette (L81) models have a very simple computerized ignition timing system. There is very little diagnostic information available with these cars. The GM shop manual is recommended for this vehicle. The ALDL connector is under the center console ash tray.

1982 Corvette (L83 Crossfire) models had a more detailed ECM, much like later vehicles. The location of the ALDL connector is under the center console ash tray. The diagnosis is more simplified, but similar to later vehicles.
