My pedal got to where it just quit responding at times and the engine light would come on and off when the pedal worked again. So I had it scanned and showed PO123 so I bought new updated tps from ford and it worked for few days fine but now it is right back to the same not responding. What next?

 

how do the plugs look? water in them?

 

no all look good , no corrosion or bent pins

 

ok just making sure it wasn't a bad connection. do you know any one with a SD that you could swap it with and see if the TPS is bad?

 

Found my problem, was a wire under the master cylinder that had the insulation rubbed into and was all corroded up.
