Sorry to jack the thread but I have the same issue my tps reads 4.9v and drops as I open the throttle. There are 3 wires. I am reading the voltage from the bottom wire. the car has no power untill I hit over 55mph.

Hi, I think I have the same problem. I just got my engine rebuilt. I started it today, everything vent good, car started, i adjusted timing. Now if I press down the gas nothing happens it stays running around 900 rpm's. Not sure whats going on.
