2006 Ford Cutaway
Mileage163,105Service Date5/1/2025Services Performed- Blend Oil. Change oil and oil filter.
- FREE MULTI-POINT SAFETY COURTESY CHECK/*D.V.I*
- -TECHNICIAN FOUND MULTIPLE STAGES TO THE ISSUES AS FAR AS THE POOR RUNNING CONDITION OF THE VEHICLE. WE HAD A FUEL PUMP DRIVER CODE (P1233) DUE TO A ROTTED OUT FUEL PUMP CONTROL MODULE AND CONNECTOR WHICH WE REPLACED TO ALLEVIATE THAT CODE. IT ALSO HAD A P0351 FOR IGNITION COIL A PRIMARY/SECONDARY CIRCUIT. IT WAS THROWING THIS CODE ULTIMATELY DUE TO A FAILED PCM , WHICH WAS ULTIMATELY DETERMINED AFTER EXTENSIVE TESTING AND DIAGNOSIS TO ELIMINATE ALL OTHER POSSIBLE AVENUES THAT COULD BE CAUSING THIS. PULLED OUT SPARK PLUGS ALSO, WHICH LOOKED HORRENDOUS AND NEEDED REPLACEMENT. SHOULD BE DONE EVERY 60K MILES MINIMUM. REPLACED COIL ON PLUG BOOTS WHICH TORE DUE TO HEAT/BECOMING BRITTLE , WHICH WITH DISASSEMBLY MAKES IT SO THEY CANNOT GO BACK TOGETHER. VALVES SEEM TO NOT BE SEALING TOTALLY AT IDLE CREATING A LITTLE BIT OF WHAT WE WOULD CALL RUMBLE, BUT THE THING RUNS AWESOME UNDER LOAD,, THIS OCCURS DUE TO DRIVING IT AROUND WITH A MISFIRE, WHICH BREAKS UP THE CARBON IN THE MOTOR, WHICH CAN THEN GET WEDGED UNDER THE SEALS-CAUSING THEM TO NOT BE ABLE TO SEAL CORRECTLY AND IDLE ROUGH. ADDED FUEL ADDITIVE TO HELP COMBAT THIS/HOPEFULLY GET THEM TO SEAL BETTER, BUT IT IS NOT GUARANTEED. ENGINE HAS A LOT OF MILEAGE AND WEAR ON IT, BUT IT RUNS 1000x BETTER THAN WHEN IT CAME IN AND WE HAVE ALLEVIATED ALL ENGINE CODES.
- REPLACE FUEL PUMP DRIVER MODULE AND CONNECTOR
- FUEL FILTER – Remove & Replace – Gas
- DIAG-INSTALL PCM
