Had the computer read and it came up maybe a vacuum leak. My gas cap does pop off sometimes. Car is running great. This happened last summer stayed on for a week then went off. Now it came on again and don't know what the problem is.

    probably the gas cap is the problem, without the check engine light code its just guessing. make sure the cap is correctly installed when refueling.

    I think it is something small like the gas cap because when I left the house yesterday the light was off. I have the codes and I'll post them for you when I can. Thanks so much for responding. I was happy to see the light off which makes me think it is nothing serious. :-)

    Is it the original cap? Have seen some aftermarket's that dont fit so good. Do you know if it had an EVAP code?
