I have a 2003 Toyota Corolla with 96,500 miles on it. It is now idling rough at stop lights and recently the check engine light came on and went off so I did not get it checked. What could it be?

That Check Engine light might be a clue as to what the problem is. If there’s an AutoZone store near you, they’ll plug in a code reader and pull the codes from the computer. Once you get the code number, post back and someone might be able to help you out.
