The service engine light can come on for many different reasons if you take it to a dealer/mechanic they can pull a code to let you know what part of the system is failing it could be something simple or something major there is a way to jump a wire but I am not sure which ones to cross in the diagnostic connector. Hope that helps
the computer tells it to glow.
The problem was not fixed with a tune up, or the light is on because it was not reset by the service station.

A service engine light can come on for many reasons. Someone can take the vehicle to the dealership or auto parts store to have them read the code and let them know what the issue is.
Engine vibration can be an indication of a misfire, but more often it's just the AC compressor causing a little shaking.
That is one of many possible causes.
Have vehicle scanned to have codes cleared
