Can a car cutting out with check engine light coming on?

Yes, a car cutting out with the check engine light coming on is a common symptom of a variety of problems. The check engine light doesn't pinpoint the exact issue, but it indicates a problem the car's computer has detected that might be causing the car to stall.

Possible causes include (but are not limited to):

* Fuel system problems: A clogged fuel filter, faulty fuel pump, or low fuel pressure can cause the engine to starve for fuel and cut out.

* Ignition system problems: Issues with spark plugs, ignition coils, or the distributor (in older vehicles) can prevent the engine from igniting the fuel-air mixture.

* Mass airflow sensor (MAF) problems: A faulty MAF sensor provides inaccurate information to the engine control unit (ECU), leading to improper fuel delivery and potentially stalling.

* Crankshaft position sensor (CKP) problems: This sensor tells the ECU the position of the crankshaft. A malfunction can cause the engine to misfire or stall.

* Throttle position sensor (TPS) problems: Similar to the MAF sensor, a faulty TPS provides inaccurate information, leading to poor engine performance and potential stalling.

* Computer (ECU) problems: In rare cases, a problem with the ECU itself can cause the engine to cut out.

To diagnose the problem, you'll need to have the car's diagnostic trouble codes (DTCs) read using an OBD-II scanner. This will give you a better idea of what the car's computer has detected. Ignoring the problem can lead to further damage or more costly repairs. It's best to take the vehicle to a mechanic for diagnosis and repair.
