ya the light has not came back on ,so we'll see. but before replacing the purge solenoid were you smelling a odor of gas inside your car.because the other day i was smelling a odor of gas in my car, do you think that could be it...thanks

I did but my main symptom was that when I went to the gas pump the auto shut off on the pump would go off when I only had like a 1/4 of a tank in there. It wasn't just one gas station either it was at every one I went to. I could still pump gas just had to do it slow and stop every once and a while to let it settle in the tank. What was causing it to do that was the solenoid not venting the tank.
