I talked to the guy that is selling one by me and he said the check engine light is on due to something wrong with over filling the gas tank? Dealership quoted him $300 to fix. Anyone every heard of that?
Sounds like the charcoal canister in the evap system got saturated from the overfill and it's throwing a code. I think it mentions this somewhere in the workshop manual. Probably just replace the canister, or if you're offroading it only, then don't worry about it. BTW like your racelines, are the rims pretty light? I am on the fence between those and some heavier Hutchinson double locks.
