I have a 2005 crown vic p71 motor and trans in a 73 f100. I have a ron Francis standalone harness and tune for it and I'm having trouble getting it going. I'm getting a p0121, p0221, p2105, p2107, and u0300. Everything points to the throttle body and possibly apps sensor. I have replaced the entire throttle body with new tps and the new throttle motor. That did not change anything so I replace the entire pedal assembly and still nothing. All wiring has been checked and rechecked about 10 times and I'm just at a loss from here and not sure what to check. Any advise at all would be a great help.
