I turned off and back on then it was drivable engine light on epc light keeps coming off and on

My car has 142000 miles.
My car has an automatic transmission.

Hello. Since the check engine light is on the best thing to do first would be to scan the computer for codes. This would need to be done first to see what the computer is seeing as the issue. It sounds like it may be a problem with a bad sensor reading or maybe from a misfire caused by the lack of a tune up or an issue with one of the ignition coils.
