4. Engine Knocking
Engine knocking can occur due to improper tuning or insufficient fuel quality, leading to severe engine damage if not addressed promptly.
Symptoms of Engine Knocking
- Audible knocking or pinging sounds from the engine
- Decreased power and responsiveness
- Potential check engine light activation
How to Fix Engine Knocking
To resolve engine knocking issues, follow these tips:
- Ensure proper tuning of the engine management system.
