I disconnected battery and, check engine light was off until I got up to 45 mph and light came back on. Any suggestions. Also, car has 270,115 miles on it and, runs great even with light on.

    You will need to get a diagnosis on your vehicle by a qualified mechanic. To me, it sounds like a fuel control issue (oxygen sensor, etc). Not entirely sure, the diagnosis will tell you everything you need to know. Good luck.

    Disconnecting the battery won't clear the trouble codes or fix anything. If the light's on, it's indicating that the computer detects a fault in the sensors and control systems. It should have data and trouble codes stored in the computer and you need a scanner to access that information. Then you can fix the car. With that mileage, the first thing I suspect are oxygen sensor or catalytic converter problems which you may not notice driving the car.

    Thanks for the imformation. I replaced all 3oxygen sensors last year. I did notice that when the light is off, It has very quick acceleration.

    Thanks again.
