Subject: Re: Check engine light (check the gas cap)


I don't have the problem now -- thank goodness! It was maddening while it lasted, and absorbed a great deal of my time in trips to the Saab dealers, etc. I'm satisfied that it never had anything to do with the gas cap. Initially, the light came on for the first time when I was just driving along an expressway, not having recently removed the gas cap. Secondly, one of the things I did when I was still laboring under the gas cap delusion was to go to a local emissions testing station and ask them to check the gas cap. They found it was fine. I don't want to generalize from my particular case. However, I do wonder whether the gas cap theory is not mostly just a convenient way for mechanics to explain an elusive problem, in the process shifting the blame to the customer.
