I'm lookin into buying a used car. There's one that seems to be a pretty good deal, but apparently the Check Engine light is on, and the guy says it's due to a faulty gas cap. Now I don't know much about cars at all, and I Googled and couldn't find what I needed...so is this a relatively serious problem? Costly fix? Will it effect MPG? Or would you just move onto the next vehicle?

This happens in a lot of cars from what I have heard.

^^^ This. I would go with the guy to the service place and make sure before you buy it, have them look at it.

GM cars that have OEM 2 need the engine system to be pressurized in order to run right. A loose or non sealed gas cap will cause the check engine light to come on. Take the car for a test drive and while on the test drive take it to Autozone and have them pull the engine codes for your answer if that is the real reason. I believe they will pull your engine codes for free.

Correction OBD 2 not OEM 2. My automatic correction changed that on me and I didn't notice.

Thanks for the input...goin to see it tomorrow and will swing by Autozone.

My 1997 Lumina had 147,000 miles when I got it in August of 2005 and the check engine light was on.

The check engine light stayed on till it hit 185,000 miles then went out so I figured it burnt out.

At 195,000 miles it came back on and is still on to this day at 205,000 miles.

Could have not reset the ECM after service or the car ECM is telling you that a oil change is needed
