This morning, the "check engine" light went out. I went to the auto repair garage & explained the situation to the fellow there. He believes the problem is the gas cap, but there wasn't any testing done. He did say that although my car is a 2004, the gas cap can be considered "old" & the caps are made of aluminum which has a tendency to break down after a while. I purchased the new gas cap, so will wait to see if the engine light comes on again.
Steve Says,
I'm glad you found someone who seems to know what they are talking about! I hope this fixes it and you have no more trouble. Thanks for the update!
