I have a constant check engine light on my 2003 Acura TL which I continue to drive. The car is hesitating and the gas mileage has taken a dive. Last year I had the same issue and I poured Restore in the tank and the light went out. This time it was a no go. According to the manual the problem lies within the emission system- what would be your first guess as to the cause of the light? Thanks for your time. Tim B.
