My check engine light keeps coming on but after I get gas the light goes off and then will come back on a couple days later. I'm thinking it may be the seal for the gas cap or the gas cap itself causing sensor to trigger but I may be wrong. I had it scanned at Advanced just as a quickie on my way to work and it said "Manufacture Air/Fuel Module." Which basically means I would have to take it to the Stealership to have them run the code and see what the actual problem is. I don't want to take it to them just for the simple fact most of them will give you a run for your wallet. Any ideas are appreciated.

I had a similar problem but my car was throwing 3 codes. I had Autozone clear them all and I ordered a new gas cap from rockauto.com (great site IMO). Also, make sure you are tightening the gas cap at least 3 clicks. I will try to find the link to the actual part on that site just in case you care to try that option.
