I have decided to share my mistake just in case someone else does it: Friday I filled my baby up with gas and accidently left the gas cap in the holder on the door. While driving later the check engine light comes on. After checking all the basics I couldn't figure it out so I figure it was just a false alarm. This morning I put gas in and see the cap on the door and am very thankfull Nissan has that holder. I replace the gas cap, drive off and 5 minutes later the check engine light goes off.

 

happens to alot of people on all sorts of cars.

Smile, thats all it was.

 

i wonder what the code came in as?

 

But I know my cold air intake gas tank setup didn't help.

 

I was thinking the same thing...
