My wife took the carinto town today and an hour or so later she called and said the car would barely go, it would sputter (she said) and then she would let off the gas and it would slowly build up speed, so I came home and took it for a drive, if you barely step on the gas it will slowly build up speed without shifting at all so I thinks its stuck in 3rd gear. When I step on the throttle it just falls flat on its face. I took it to a parts center and the read code that said epc, 1st, 2nd, 3rd solenoid open or shorted circuit. Did all these go bad at once or is it the epc causing all the problems? Is it a fairly easy fix from underneath?
