Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello, if the gas cap was the issue it will take 50 key cycles and drive cycles (from cold to hot engine) with no codes for the light to reset, it will be quicker to run to autozone and get the codes read and also have them erase them. then we can double check the code to see if it was relating to the gas cap or not. hope this helps, Lou P.
