My check engine light came on a couple days ago, it hasn't affect engine performance. I had been getting a gas cap needs to be tightend alarm, and someone told me that may be the problem. Anywho was just wondering what kind of problems it could be, it didn't come with a manual when I bought it, so thank you for your time.

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on.
