I have a 99 4.6 expedition that stumbles or sputters at about 1500 RPM's checekd coils and IAC last night just got to the TPS and got a bad Voltage reading but I have no codes or check Eng light on is this posable to have a bad TPS and no codes or check Eng light on????
Yes, it could be. They don't cost much, I would go ahead and replace it. It is really nothing more than a rheostat and the will get a bad spot in them over time.
