A spark plug that is under-torqued will not be entirely seated in the cylinder head, which reduces heat dissipation. As a result, the spark plug’s firing end may overheat and pre-ignition can occur. Metal shell stretching can occur as a result of excessive torque.
Worn or unclean spark plugs may cause a petrol automobile’s engine to malfunction in one or more cylinders, resulting in vibrations when the car is idling or accelerating. Replacing your spark plugs and double-checking the wiring is the most straightforward approach to get rid of these issues. Engine vibrations can also be caused by air and fuel systems.
