2000 olds alero 2.4 liter, the engine soon light is on , auto zone says it is a seal, they thought gas cap was loose but i put a new cap on, still didn't solve the problem, the light did go off for about 3 days but came on and has stayed on , they said something about it just being a seal, but which one?the other question is could it be the fuel pressure regulator by chance, i did get some contamaited gas a few months back and they put a sock over the filter in the tank. or maybe a valve sticking and if so which one and where do i look for it?..
