ok so my car went into limp mode i think i was driving and it started acting weird then all the sudden it sputtered for a second so i tryed to rev it and it wouldnt rev past like 3k i think and it wasnt slow it was like there was a rev limiter at 3k i turned it off and let it sit and now it is fine but the car keeps overheating randomly and is having charging problems so any help would be helpfull thank you
