Hello everyone:
Recently my brand old 1988 Plymouth Voyager SE (V6 3.0 L Engine) started to hesitate while accelerating and maintaining a steady speed. This usually happens within 10 minutes of driving with the engine warm. The Tachometer shoots up and down. I step on the gas, but it doesn't kick in until the RPMs go down to 1000 or less. The idle speed is between 800/900 RPMs.
So far I've changed:
- Spark plugs/cables (it was time to change them anyways) * Fuel filter (what I thought to be the problem, but wasn't) * Air filter * Throttle Position Sensor (still no change) * PCV valve
I did the on, off, on, off, on ignition thing to check the trouble codes and I get:
code 24 - Throttle Position sensor voltage low/high code 36 - Wastegate control circuit open or shorted (turbo only) code 37 - Torque converter unlock solenoid circuit. An open or shorted condition detected in the torque converter part throttle unlock solenoid circuit(automatic transaxle models only)
If the TPS voltage is too low/high, what would cause/fix this problem? What else could be causing the hesitation?
Thanks!... Any feedback will be appreciated...
