- The fuel pressure regulator (FPR) controls the fuel pressure in the fuel system. A faulty FPR can cause the fuel pressure to be too high, resulting in flooding.
2. Leaking fuel injectors:
- Leaking fuel injectors can cause fuel to continuously flow into the cylinders, even when the engine is not running. This can lead to flooding.
3. Faulty oxygen sensor:
- The oxygen sensor measures the amount of oxygen in the exhaust gas. A faulty oxygen sensor can cause the engine to run rich, which can lead to flooding.
4. Blocked air filter:
- A blocked air filter can restrict airflow to the engine. This can cause the engine to run rich, which can lead to flooding.
5. Faulty mass air flow sensor (MAF):
- The MAF sensor measures the amount of air flowing into the engine. A faulty MAF sensor can cause the engine to run rich, which can lead to flooding.
6. Faulty throttle position sensor (TPS):
- The TPS sensor measures the position of the throttle plate. A faulty TPS sensor can cause the engine to run rich, which can lead to flooding.
7. Vacuum leaks:
- Vacuum leaks can cause the engine to run lean, which can lead to flooding.
8. Computer sensor/module related:
- If multiple sensors or modules simultaneously begin to fail/misbehave, it will often confuse the computer to the point that the engine will run extremely rich or lean.
