Chevrolet Corvette Check Engine Light Due to Gas Cap Issue
Chevrolet Corvette Problem

I've had the gas cap replaced twice in 24 months ... and it's still difficult to ensure that it's properly closed.

Had Dealer replace gas cap, but doesnt seem too secure. I hope Chevy can come up with a more secure gas cap.
