How appropriate, the Knight has a Mustang.

Check your vac line to the EGR. If you knock it loose, you'll spit a 332. If not, ensure the EGR position sensor is connected to the EGR valve.

You can put a vac pump on the line to the EGR and see if the engine stalls or nearly stalls when you apply 6 or so inches of vac to the EGR port. If not, the EGR passageway is coked or the EGR itself might be bad (diaphram).

You can also make sure the plastic line to the EGR didnt break (and now leaks). That would cause an issue and the lines are known for breaking.

Sometimes the fuel codes are bonafide (assume it is) but sometimes they are ghost codes. For instance, if you stall the car or trip the inertial switch, the FPM can take note of this and create a code.

Good luck.
