How to Deal with Engine Shaking?
2 Answers
Reasons and solutions for engine shaking are as follows: 1. Dirty air filter: The air filter is designed to protect the engine and reduce wear, usually requiring replacement around 10,000 kilometers. If not replaced in time, insufficient air intake can cause low idle speed, leading to engine shaking. Simply replacing the filter can solve the problem. 2. High-voltage line break: A high-voltage line break refers to the breakage of the conductor core inside the high-voltage line, causing engine shaking. Use a multimeter to measure the resistance and replace the one with significantly higher resistance. 3. Spark plug lifespan: Spark plugs have a lifespan, and after 30,000-40,000 kilometers, their ignition efficiency significantly decreases, affecting ignition. This is the most common issue, and replacing all spark plugs can resolve it.
I've been driving for many years, and when the engine shakes, I usually start checking from the easiest points. Last time I encountered this issue, I manually inspected the spark plugs. Worn-out spark plugs can cause irregular ignition in a cylinder, leading to noticeable overall shaking. Then, I checked the air filter—if it's too dirty, air can't get in, causing unstable engine operation, so it needs regular replacement. The fuel system is also a key focus. Clogged fuel injectors can lead to deviations in the air-fuel mixture concentration, causing shaking. I tried adding some cleaner to solve minor issues. Additionally, aging engine mounts or loose screws can transmit extra vibrations, which require professional tightening. Don't delay the whole process; address it early to avoid burning oil or affecting other components. Simple tools can handle DIY checks for most situations—it's time-saving and practical.
