I have a Cavalier 98 with 150000 miles, I have noticed that about a week ago the check engine sensor was on when driving my car, however I saw that when the car is full of fuel, the sensor goes of, that didn't happen before, so I dont know what is happening, the car runs great, however yesterday I was driving the car and suddenly it began to behave as if there was a problem with the fuel, like the motor wasn't getting enough fuel, and the car was lossing power, I saw the sensor and I saw that the check engine sensor was blinking, I stop the car and turned it off, to see possible damage in the engine, I didnt see nothing so I continue my way and the check engine sensor stop blinking but continue to be turned on, today I fill my car with gas and the check engine sensor is again off.

Any Idea of what's going on?

Sorry for my pour English

Have your engine codes checked it should point you in the right direction.

First-off, before getting the codes checked, replace the fuel filter. If the filter hasn't been replaced in a while, then that would be a good idea. This tends to be the cause of the problem. Afterwards, if it's still behaving erratically, go farther down the fuel line, Checking the fuel pump, the lines, and injectors. I suggest that if you're not a do-it-yourself type of person, it would in your best interest to take it to a professional. Besides all that, do check the codes at a dealer, since that might also help diagnose the problem.
