The ignition switch is responsible for providing power to the starter motor and other electrical components when you turn the key. If the ignition switch is faulty, it may not be able to provide enough power to the starter motor, resulting in a rough start and misfires.
2. Bad fuel pump:
The fuel pump is responsible for delivering fuel to the engine. If the fuel pump is faulty, it may not be able to provide enough fuel to the engine, resulting in a rough start and misfires.
3. Clogged fuel filter:
The fuel filter is responsible for removing dirt and debris from the fuel. If the fuel filter is clogged, it may restrict the flow of fuel to the engine, resulting in a rough start and misfires.
4. Faulty spark plugs:
The spark plugs are responsible for igniting the air/fuel mixture in the cylinders. If the spark plugs are faulty, they may not be able to produce a strong enough spark, resulting in a rough start and misfires.
5. Faulty ignition coil:
The ignition coil is responsible for providing a high voltage spark to the spark plugs. If the ignition coil is faulty, it may not be able to provide enough voltage to the spark plugs, resulting in a rough start and misfires.
6. Bad oxygen sensor:
The oxygen sensor is responsible for measuring the amount of oxygen in the exhaust gas and sending this information to the engine control unit (ECU). If the oxygen sensor is faulty, it may send incorrect information to the ECU, resulting in a rough start and misfires.
7. Vacuum leak:
A vacuum leak can cause the engine to run lean (too much air and not enough fuel) which can result in a rough start and misfires.
