ohh sorry 2000 ford f 250 7.3 turbo deisel

 

Can you expand on what you mean when you sat "running bad"?

Missing? Rough idle? No power?

Is the engine stock?

P0470 Exhaust Back Pressure Sensor Circuit Malfunction
P0478 Exhaust Pressure Control Valve High Input
P1670 EF Feedback Signal Not Detected
P0603 Internal Control Module KAM Error
P1316 Injector Circuit/IDM Codes Detected

 

yes the engine is factory stock with the exception of the hyper tech programmer 111

 

by running bad i mean it will barley move

 

Welcome to FTE. For future reference, we have a 7.3 diesel specific section located further down the main forum listing. Your problem is the P1316. Odds are the UVCH came loose on one side. That's your under valve cover harness.
