Fuel System Problems:
1. Fuel Filter Clogging: A clogged fuel filter restricts fuel flow to the engine.
2. Fuel Injector Issues: Faulty fuel injectors may not deliver the right amount of fuel.
3. Fuel Pump Failure: A failing fuel pump can't provide sufficient fuel to the engine.
Ignition System Problems:
1. Spark Plug Issues: Worn or fouled spark plugs can cause misfires.
2. Spark Plug Wire Problems: Damaged spark plug wires can lead to misfires.
3. Distributor Issues: Problems with the distributor (in older vehicles) can cause ignition timing problems.
Air Intake Issues:
1. Dirty Air Filter: A clogged air filter restricts air intake.
2. Mass Air Flow Sensor Issues: A faulty mass air flow sensor can lead to an incorrect fuel mixture.
Electrical System Problems:
1. Loose or Corroded Electrical Connections: Bad connections can disrupt power supply.
2. Alternator Problems: A failing alternator may not provide enough electrical power.
3. Battery Issues: A weak battery can cause electrical problems.
Vacuum System Leaks:
1. Vacuum Hose Leaks: Air leaks can lead to a lean fuel mixture and power loss.
Engine Problems:
1. Engine Control Module (ECM) Issues: Faults in the ECM can affect fuel injection and ignition timing.
2. Mechanical Problems: Malfunctions within the engine, such as worn or damaged parts, can result in power loss.
3. Compression Issues: Low cylinder compression can cause power loss.
It's important to get your car diagnosed by a mechanic if you're experiencing stalling, sputtering, or loss of power to determine the exact cause and ensure safe and reliable operation.
