Use this as a reference for the TPS: Ford Fuel Injection » Throttle Position Sensor (TPS)

Many times when the VSS has a problem it will trigger a code, but for you that is not the case. If the TPS appears okay, then I would suggest trying a new VSS.
ok thanks so much, im going to look at the TPS, I think i replaced the VSS years ago. Ill report back
