Do gas caps go bad?
What is your question?
I had a check engine light come on a year and half ago and the dealer charged $99 to diagnose and tell me the gas cap was bad. So I replaced cap. Again, Check engine light comes on, Dealer charges $99 to diagnose and then say it is a bad gas cap. For $100 couldn't I buy one of those stupid machines that would tell me what the code is? Next time I think I will just buy a new gas cap.

gas caps orings do go bad all the time. as far as your buying a code reader yes you can but don't start replacing parts based on a code. the code only indicates the circuit that is failing not the part.so be careful and don't just throw parts at it.
