2. Faulty fuel pump: A faulty fuel pump can't deliver enough gas to the engine, leading to similar problems. Check the fuel pressure and pump operation to diagnose a faulty fuel pump.
3. Bad spark plugs: Bad spark plugs can prevent the engine from igniting the fuel properly, leading to misfires and stalling. Check the spark plugs and replace them if they're worn or damaged.
4. Faulty ignition coil: A faulty ignition coil can't deliver enough voltage to the spark plugs, leading to misfires and stalling. Check the ignition coil and replace it if it's faulty.
5. Vacuum leak: A vacuum leak can cause a lean air-fuel mixture, leading to engine hesitation, stalling, and rough idling. Check the vacuum lines and seals for any leaks and fix them accordingly.
6. Throttle body issues: A dirty or faulty throttle body can disrupt the air-fuel mixture, causing stalling, idling problems, and poor acceleration. Clean the throttle body or replace it if needed.
7. Mass air flow sensor: A faulty mass air flow (MAF) sensor can provide incorrect air flow data to the engine, affecting the air-fuel mixture and leading to stalling and rough idling. Check the MAF sensor and clean or replace it as necessary.
8. Faulty oxygen sensor: A bad oxygen (O2) sensor can provide incorrect feedback to the engine's computer, affecting the air-fuel ratio and leading to stalling and other performance problems. Check the O2 sensor and replace it if it's faulty.
9. Fuel injector problems: Faulty fuel injectors can cause incorrect fuel delivery, leading to stalling, misfires, and rough idling. Check the fuel injectors and have them cleaned or replaced as needed.
10. Computer (ECU) issues: Rarely, a faulty engine control unit (ECU) can cause a variety of problems, including stalling and rough running. If all other components check out, have the ECU diagnosed by a qualified mechanic.
Remember that diagnosing and fixing car issues can be complex, so if you're unsure about the cause of the problem or don't feel comfortable doing the repairs yourself, it's best to consult a qualified mechanic for assistance.
