Issue after ground came loose

[BuellRiderX]

I was riding home one day when the bike just died on me. Coasted to a stop and pulled off the seat. Turns out the ground bolt on battery had vibrated loose. Hand tightened it and went on my way. 1 min into riding and the bike stumbles/hesitates and check engine light comes on. Next day I go for a ride and it's doing the same thing. It'll stumble, check engine light comes on. After 10 mins of riding it'll run just fine but engine light is still on. Recently it got even worse. If I give it more than quarter throttle or above 3k rpms it stumbles. Any ideas?

Try a tps reset.. I do a tips reset about 2 times a month just to make sure its good.
