Just started to have an annoying problem with my 2000 maxima (30,000 miles).
I fill the car with gas, drive about 15 miles, and the service engine light comes on and stays on. I reset it by disconnecting the battery for an hour, and it stays off untill my next fill up and then the same thing - drive about 15 miles and the light comes on.
I know that if the gas cap is not tighten properly this can happen, but the cap is secure, and the gasket on it seems OK. I first thought that it was a fluke, as a friend of mine "topped off" the tank when he filled the car the first time this happened. I thought maybe he just got some liquid gas into the canister system. But now its happening everytime I fill up the car - even at different service stations.
Otherwise the car runs fine.
Has anyone seen this problem before?
