And without a tps code, non of that should have anything to do with his problem.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

You have to adapt a Fox Mustang 5.0 HO tps sensor to make the 65mm explorer throttle body work.You will not be giving the pcm the correct signal if you use the explorer tps as the voltage range is different on both types of tps sensors.
 here is the link you need. I do not know your car but I have to assume that you are running HO stang electronics if you are bolting on a 65mm tb.

this is the same write up i got when I bought the Explorer 65mm from ebay.  Weird thing though,  the TPS that came with it had a different connector but the screw spacing was identical.  The thing I'm noticing now is that the surging has pretty much stopped.  the only thing it does now is occasionally get 'caught' idling too high when I start it warm -- and it will continue too high until I turn off the engine and restart.  then it is perfect for the rest of the drive.
