I own a Nissan Maxima 2000. A few weeks ago, the check engine light
came on. I went to Checkers and got the readout - the code was P1320 -
I think the text that went with it was like "ignition or misfire". A
few days after that, it went out and stayed out for at least a week.
On friday, the light came back on - I was sitting at a red light, and
the car sort of shuttered a little bit, then the check engine light,
TCS ON, and one more light (forget text for this - it's no longer on)
came on and stayed on for the duration. Subsequent startups and it's
just the check engine light on.

I don't want to go in for unnecessary "repairs". Is this anything I
can look into myself? I did notice that both times, I have filled up
the tank the night before, and the next day, the light comes on. Can
this be mere coincidence? The gas cap is on tight. Think I should try
replacing it?

Thanks in advance,
