- Fuel system issues: A clogged fuel filter, faulty fuel pump, or a problem with the fuel pressure regulator can cause the engine to cut out.
- Electrical problems: A loose electrical connection, a malfunctioning ignition switch, or a faulty ignition coil can also lead to cut-outs.
- Engine problems: A mechanical problem with the engine, such as a faulty camshaft sensor, a damaged timing belt, or a low compression ratio can cause the engine to stall.
- Air intake issues: A blocked air filter or a problem with the air intake system can cause the engine to run lean and cut out.
- Computer problems: A problem with the engine control unit (ECU) or its software can also cause the engine to cut out.
- Fuel mixture: The fuel mixture may be too lean or too rich, which can cause the engine to stall.
- Vacuum leak: A vacuum leak can cause the engine to run lean and cut out.
- Bad O2 sensor: A faulty oxygen sensor can cause the engine to run too rich or too lean, which can lead to stalling.
- Engine overheating: If the engine is overheating, it may go into limp mode and cut out to prevent further damage.
- Damaged crankshaft or connecting rod bearings: Worn or damaged crankshaft or connecting rod bearings can cause the engine to lose compression and cut out.
If your car keeps cutting out while driving, it's vital to have it diagnosed and repaired by a professional mechanic as soon as possible. Driving a car that cuts out can be dangerous and could lead to an accident.
