Why is my car hard idleing and not accelerating?

Why is my car hard idleing and not accelerating? I have 2008 Ford Explorer 4.0L engine and over 130,000 miles. My car is shaking and won’t accelerate when I push the gas peddle. I’ve replaced throttle body unit, replaced engine control computer (programmed it also), and changed the spark plugs but the car is still doing the same thing. My mechanic had put the scanner on it and he can’t figure it out either.

Out at the throttle body is the wires for the system, you may have a wire that has rubbed raw and shorted out, I have also seen 2 wires together short together so unwrap the wire harness and verify if you have bad wiring, you should not have to unwrap much, typically where the wire harness for the TPS bends, probably within a few inches.
