What problems can incorrect car timing cause?

[Cole]

Incorrect car timing can lead to unstable idle speed, weak acceleration, engine shaking, insufficient power, and in severe cases, it may cause the engine's valves and pistons to collide with each other, resulting in engine damage. The ignition timing of a car varies depending on the engine. The purpose of adjusting and correcting the ignition timing is to achieve a better ignition timing or initial ignition advance angle, thereby obtaining good engine performance. The timing system consists of components such as the timing belt, tensioner pulley, tensioner, water pump, and other accessories. There are two types of car timing: 1. Valve timing: This refers to the precise timing with which the valve train supplies the combustible mixture to the cylinder and exhausts the waste gases; 2. Ignition timing: This refers to the precise timing with which the combustible mixture in the cylinder is ignited to push the piston and perform work.
