A special svc msg was issued 10/11 for the Bullitt. It reads as follows:
Some 2001 Mustang Bullitt may exhibit a hesitation or stumble over bumps condition. This condition may be followed by the theft light flashing for a period of time, and diagnostic trouble codes (dtc's) C1284, U1147, U1262 may also be present. When diagnosing you may find no communication with the PCM. This condition may be caused by the DPFE wiring chaffing against the DPFE bracket shorting out VREF. Repair the wiring and re-route the DPFE wiring to run over the accelerator cable to prevent this condition from reoccuring.
