- A faulty CTS can provide incorrect temperature readings to the Engine Control Module (ECM), causing it to overfuel the engine.
2. Oxygen Sensor (O2) Sensor failure:
- A faulty O2 sensor can provide incorrect readings to the ECM, resulting in an improper air-fuel mixture, leading to flooding.
3. Faulty fuel pressure regulator:
- A malfunctioning fuel pressure regulator can cause excess fuel to enter the engine, resulting in flooding.
4. Leaking fuel injector:
- A leaking fuel injector can continuously spray fuel into the engine, leading to flooding.
5. Incorrect ignition timing:
- Improper ignition timing can cause the fuel to combust at the wrong time, resulting in unburned fuel and flooding.
6. Vacuum leaks:
- Vacuum leaks can cause the engine to run lean, leading to flooding as the ECM attempts to compensate by adding more fuel.
7. Clogged fuel filter:
- A clogged fuel filter can restrict fuel flow, causing the engine to run rich and eventually flood.
8. Faulty ECM:
- A malfunctioning ECM can provide incorrect commands to the fuel injectors, leading to flooding.
