1. Engine Shaking:
- When spark plugs become fouled, they can hinder the proper ignition of the air-fuel mixture in the combustion chambers. This leads to incomplete combustion and uneven power delivery, resulting in engine shaking or vibrations.
2. Engine Knocking:
- Fouled spark plugs can also cause engine knocking. This occurs because the unburned fuel and air mixture can create excessive heat in the combustion chambers. This leads to a condition called pre-ignition or detonation, where the air-fuel mixture ignites before the spark plug initiates the ignition. This abnormal combustion process generates a knocking sound.
3. Loss of Power:
- Fouled spark plugs can impair the engine's ability to generate power efficiently. When the spark plugs are not functioning properly, the combustion process is compromised. This leads to reduced engine power, sluggish performance, and decreased acceleration.
In summary, fouled spark plugs can cause a combination of engine shaking, knocking, and loss of power. If you suspect that your vehicle's spark plugs may be fouled, it's essential to have them inspected and replaced if necessary to restore proper engine function.
