Yep... set it to what Pinky has stated.. See if that makes a difference...

If you are still having problems you may need to get a new TPS

I didn't see a recent post about your progress, but if still need to calibrate the TPS, it'* easy but you'll need a scan tool to do it.
- Slightly loosen the 2 TPS mounting screws.
- Connect a scan tool and monitor the TPS voltage while the shifter is in Park and the key is on but the engine isn't running.
- Move the TPS clockwise or counterclockwise until the TPS voltage is near the middle of the allowed range (someone already noted it for you).
- Once the value has been reached, carefully tighten the TPS screws without moving the TPS and recheck the voltage measurement using the scan tool.
- Remove the scan tool and you're done.

If you don't have a scan tool, you can insert test pins or wires into the TPS connector'* wires and then monitor the voltage at the connector using a digital multimeter, but this isn't the ideal method.
