Services Performed
- CUSTOMER REPORTED THAT THE VEHICLE WOULD SHUT OFF IMMEDIATELY WHEN ATTEMPTING TO START, CRANKING BUT NOT TURNING OVER. UPON INSPECTION, THE VEHICLE STARTED SUCCESSFULLY EVERY TIME DURING TESTING. A PENDING CODE FOR CYLINDER 4 (P0304) WAS PRESENT, INDICATING A POSSIBLE MISFIRE; HOWEVER, THE VEHICLE WAS NOT ACTUALLY EXPERIENCING A MISFIRE AT THE TIME. DURING TESTING, ERRATIC BEHAVIOR WAS NOTED FROM THE IGNITION COIL. AS A PRECAUTION, THE IGNITION COIL AND SPARK PLUG WERE REPLACED WITH USED PARTS AVAILABLE AT THE SHOP. FOLLOW-UP TESTING SHOWED NO ISSUES AFTER THIS SERVICE. WHEN ATTEMPTING TO MOVE THE VEHICLE, THE ENGINE IDLE DROPPED IMMEDIATELY, CAUSING THE CAR TO SHUT OFF. BASED ON THE SYMPTOMS, THE THROTTLE BODY IS SUSPECTED TO NEED CLEANING. ADDITIONALLY, THE PCV VALVE WAS INSPECTED AND FOUND TO BE IN POOR CONDITION AND REQUIRES REPLACEMENT.
- REMOVE AND REPLACE PCV VALVE. THE PCV VALVE WAS PULLING ENGINE OIL, CAUSING THE ENGINE OIL LEVEL TO DROP, AND NEEDS TO BE REPLACED TO PREVENT FURTHER OIL LOSS AND POTENTIAL ENGINE DAMAGE.
- DUE TO THE BAD PCV VALVE, THERE WAS A SIGNIFICANT BUILD-UP OF OIL AND DEPOSITS IN THE THROTTLE BODY, WHICH CAN AFFECT ENGINE PERFORMANCE AND IDLE. REMOVED AND THOROUGHLY CLEANED THE THROTTLE BODY TO RESTORE PROPER AIRFLOW AND ENSURE SMOOTH ENGINE OPERATION.
