Vacuum leaks can cause a variety of problems, including power surges. When air leaks into the engine, it can lean out the air/fuel mixture, which can cause the engine to run hot and surge.
2. Faulty oxygen sensors
Oxygen sensors monitor the amount of oxygen in the exhaust gas. When the oxygen sensor is faulty, it can send incorrect signals to the engine computer, which can cause the computer to adjust the fuel mixture incorrectly, leading to power surges.
3. Faulty fuel injector
A faulty fuel injector can cause the engine to run rich or lean, which can cause power surges.
4. Faulty ignition coil
A faulty ignition coil can cause the engine to misfire, which can lead to power surges.
5. Faulty spark plugs
Faulty spark plugs can cause the engine to misfire, which can lead to power surges.
6. Faulty spark plug wires
Faulty spark plug wires can cause the engine to misfire, which can lead to power surges.
7. Faulty distributor cap
A faulty distributor cap can cause the engine to misfire, which can lead to power surges.
8. Faulty distributor rotor
A faulty distributor rotor can cause the engine to misfire, which can lead to power surges.
9. Faulty fuel pump
A faulty fuel pump can cause the engine to run lean or rich, which can lead to power surges.
10. Faulty fuel pressure regulator
A faulty fuel pressure regulator can cause the engine to run lean or rich, which can lead to power surges.
