1993 Volvo 940 Q&A
1993 Volvo 940 Question: Stalling due to mass airflow sensor?
I recently had a turbocharger replaced, and noticed the engine light on when I picked up the car. I thought nothing of it since I figured the work engaged the light, and the car had been test-driven. It drove nicely and the mechanics know this car. A few days later, when accelarating up a snowy driveway, the car stalled. Never happened in 12 years. Started right up again. Same thing happened another night. Forgot about it until yesterday, car suddenly stalled while in motion, after accelerating. Started right up again. Went here and saw this airflow sensor issue come up! I always keep tank at least half full, but the fuel filter is due for replacement. 212K miles. Am I possibly looking at a mass airflow sensor? Thank you for any help! Total time frame with this issue is about 4 weeks. - TurboGirl66
you need to take the car back to the shop that replaced the turbo. you should have immediately take the car back due to the check engine light. assume nothing until they find out what codes are causing the check engine light. - overbys
Engine stalling/stumbling problems can be caused by a failing mass air flow sensor.
