Is my tps bad?
Ok so heres the deal. When I hit the gas the car takes off slow and stops accelerating past about 2.7k rpms. I checked the voltage on my tps, at idle its reading the correct .54 volts. However at WOT its only showing 3.2 volts instead of the ~4.5 volts it should show being at WOT. Is there anything I can adjust to fix this or is this a prime example of a shot TPS?

sound like you need a new one to me, they are not expensive, it should be reading higher at WOT. Do you have a 5 volt reference on the other pin with key on?? should read right around 5 volts all the time, if that's good, then replace TPS I would say.

Yes I am getting 5 volts on the other reference wire. I will pick up a new TPS tonight and give it a try.
