How to Deal with Severe Engine Shaking?
3 Answers
Methods to handle severe engine shaking:1. Observe the engine operation condition and the degree of shaking, while also checking the swing amplitude of the engine tachometer needle to see if it deviates from the idle expectation value. If it deviates, the car engine will definitely shake, and the idle expectation value needs to be adjusted. 2. Check if there are any abnormalities in the engine external components. If there are, professional repair or replacement is needed. 3. Check if the vacuum tube is detached or damaged. If these parts are compromised, the car engine will also shake, and it's best to replace them. 4. Check if the wire connectors are loose. Loose wires can also cause engine shaking, and simply tightening them can solve the issue. 5. Check for any oil, water, air, or electricity leaks (the four leaks). Any of these leaks can cause engine shaking, so it's important to stop the leak promptly. 6. Check if the exhaust pipe emits black smoke or has a raw gasoline smell, which are abnormal phenomena. These abnormalities can lead to engine shaking, so timely repair is necessary if they occur. 7. Check if the throttle cable is properly adjusted. Improper adjustment can also cause engine shaking, and the throttle cable needs to be adjusted to the correct position.
I've also experienced severe engine shaking before while driving. That time, I clearly felt the car shaking violently when waiting at a red light in the city, even the steering wheel was trembling. I immediately pulled over, turned off the engine, and started checking. First, I inspected the spark plugs—if they were worn out, I replaced them, since spark plugs are a critical part of the ignition system. If the shaking persisted after replacement, I'd check whether the fuel injectors were clogged, as cleaning them might help. Additionally, a heavily dust-clogged air filter can affect air intake, leading to incomplete combustion and shaking. After I replaced the air filter that time, the car ran much smoother. Ignoring shaking for a long time may cause engine mount damage or carbon buildup, leading to more severe damage. My advice is to inspect it as soon as you notice shaking, and if you can't fix it, take it to a professional repair shop—never compromise on driving safety. Regular maintenance is also crucial, like checking the engine oil and filters every 5,000 kilometers to minimize risks.
I'm passionate about car DIY, and I get quite excited when the engine shakes violently—it's a troubleshooting opportunity. Generally, I start by checking the ignition system, as faulty spark plugs or ignition coils are the most common issues. I use simple tools to test resistance values and replace them if abnormal. Next, I look into fuel problems; clogged fuel injectors can be treated with cleaning additives. Air intake leaks or dirty throttle bodies shouldn't be overlooked either—I often remove and clean them myself. Loose engine mounts can cause body resonance, requiring tightening or replacement. The whole process starts with the simplest steps to save time and money, and only if ineffective do I send it for repair. Regular oil changes and avoiding low-quality fuel can prevent shaking and extend engine life. Don’t delay addressing shakes—try fixing it yourself, but stay safe.
