TPS

Let me know if you want to try my old TPS that apparently was not the problem. I think I still have it and send it to you for free if you want to try it.

Haven't found the problem yet! So far I've replaced:

- Speed Sensor
- Cruise Amplifer Module (with Junkyard unit)
- Servo

I've been scouting for vacuum leaks, reset the computer, etc. After changing above I tried plugging the vacuum line for the brake pedal switch - no effect either.

I'm running out of ideas, other then the TPS.

Anyone else?
