I was truly happy after 2 years with another mechanic, the engine light continues to come on, but whenever I would take my car back to him he stated that he could not find no problems and suggested that I tightened my gas more carefully. I became feed up with his remarks which made me feel as if their was no way finding what was actually wrong with my car. My brother suggested that I take my car to they and in about 2-3 hours they found the problem. I was elated and thankful now my emission problems are a thing of the past.
