Report: Rough Idle, Stalling and Check Engine Light Is On
Volvo S80 Problem
Average Mileage: 122,500 mi (106,000 mi - 139,000 mi)
During the diagnosis of the symptoms the technician may pull diagnostic codes from the Engine Control Module that point to a lean air/fuel mixture. If no vacuum leaks are found, then the mass air flow sensor (MAF) is often the cause.
Replacement of the MAF will be needed, along with a reset of the Engine Control Module and erasing of the diagnostic trouble codes.
