What does a car feel like when the timing is off?

[OIan]

Incorrect timing can cause delayed ignition, weak acceleration, engine shaking, insufficient power, etc. It is recommended to go to a 4S shop to adjust the timing belt and restore vehicle performance. The following are specific manifestations of incorrect timing faults: 1. Small timing deviation: In cases of small timing deviation, the car will feel weak, making it difficult to accelerate when going uphill. 2. Larger timing error: In cases of larger timing errors, the fault manifestations include no idle speed or severe engine shaking at idle, a popping sound from the exhaust pipe when accelerating, and occasional engine stalling accompanied by the popping sound. 3. Excessive timing error: If the deviation is too large, the engine may not start at all. In some car models, you may hear a knocking sound inside the engine when cranking, which is the sound of pistons hitting the valves.
