I have an 02 Hyundai accent 1.6L automatic with 103,000 miles. I have replaced. Both o2 sensors, plugs, wires, all fluids and filters, MAP sensor, flex pipe, ran sea foam, replaced fuel cap, and PCV valve. I'm getting terrible gas millage, bad acceleration, and slightly over revving. I get about 20MPG no matter where I go, If not worse. BUT if I reset my PCM the car runs like new for 80 miles. Please help me. I'm out of ideas.
have the same problem?
