Hi, I have a 2000 Maxima and I had my imission check, and I think about a week later my check engine light came on. It goes off about a month later but comes back once in a while. It went off when I had low gas in the car I think. The book says to check the gas cap and stuff, and I think I did, when I fill up I make sure that the cap clicks a couple of times. Can anybody help.....thanks
