Default Check engine after fuel door install

After installing the popular fuel door in place of the stock plastic housing, I'm now getting a check engine light (small evap leak) and a 'gas cap' message in place of my odometer. I've replaced the gas cap fearing the O ring wasn't making a complete seal, but still the same problem. Also, the filler neck seems to have more wobble than it did, and more than other JKs I've driven. Any idea where to start tracking this down once the weather warms up?
