It's got 124K on the engine and it just started to have problems. The engine seems to shudder between 45-65 mph while maintaining speed. During acceleration this does not happen. I thought it might be mis-firing at first but then it should do it all the time not just at 45-65 mph. I heard it could be the Throttle Position Sensor which make sense to me but I have received mixed opinions from my local parts stores. Can any one help?
X the TPS.I feel the problem is not in the motor,sounds like a bad Ujoint in driveshaft,or a bent or out of ballance tire.also it is possable the tourk converter is going bad.
