Engine code P0650 volvo c70 - 1999 Volvo C70

SOURCE: engine chugging

Sounds right. Either Coil pack(s) or MAF sensor. Buy one and swap it out until you find bad COP (coil on plug). Each spark plug has one and there is not really a good way to test under stress. MAF sensor is just past the intake air filter. You can buy a spray at the auto store to clean this, which may help. Don't touch the sensor itself (ith your finger) as this will ruin it. Just soak it with the spray.

90% of the Time..Code 1171 is an 02 sensor. Other 5% Is a Mass Airflow Sensor.. And Last .. Fuel Pump.. If engine seems to run fine.. its an O2 sensor.. Thank you
