What Causes Car Shaking While Driving?
2 Answers
Reasons for feeling car shaking while driving include: 1. Dirty throttle body; 2. Excessive carbon buildup in fuel injectors; 3. Poor ignition system performance, weak spark plug firing; 4. Abnormal fuel pump pressure; 5. Faulty or incorrect readings from the intake pressure sensor; 6. Worn-out engine mounts. Solutions for car shaking are: 1. Clean or replace the air filter; 2. Use a multimeter to measure resistance and replace wires with high resistance; 3. Maintain the engine operating temperature within the normal range; 4. Clean the fuel injectors; 5. Replace spark plugs; 6. Clean the fuel system and idle control valve; 7. Replace engine mounts.
My car suddenly started shaking while I was driving, which was quite annoying. The most common reasons are unbalanced tires or uneven wear, and if the wheel dynamic balance isn't properly adjusted, it will wobble at high speeds. Incorrect tire pressure, whether too high or too low, can also affect stability while driving. Additionally, issues with the suspension system, such as worn-out shock absorbers, can make the shaking more noticeable on bumpy roads. Warped brake discs can cause the steering wheel to shake when braking, making it feel like the steering wheel is vibrating. If the shaking occurs during acceleration, it's likely due to damaged engine mounts—when those rubber mounts break or deteriorate, engine vibrations transfer into the cabin. Loose ball joints in the steering system can also cause shaking when turning. I recommend pulling over to check tire pressure and wear first; if that doesn't help, take it to a repair shop for a professional diagnosis. Don't ignore this issue—it not only affects comfort but also poses a safety risk. Addressing it early ensures a more secure and worry-free drive.
