I have had the "check engine" light come on for other vehicles and never return so did not figure out what the computer thought was the problem. I have often wondered if that "gas cap" situation applies to all computer controlled or just some of them.

We have also done much parking lot touring.:B Especially if there are antique stores nearby.
