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)
* Throttle Position Sensor (still no change)
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?
Any feedback will be appreciated...
