Why does the car shake and vibrate while driving?

[MacOscar]

The reasons for feeling car shake and vibration while driving are: 1. Dirty throttle body and severe carbon buildup on engine fuel injectors; 2. Problems with spark plugs, high-voltage wires, or ignition coils; 3. Deep scratches or grooves on brake discs; 4. Abnormal fuel supply pressure from the fuel pump; 5. Incorrect readings or malfunction of the intake pressure sensor; 6. Aging engine components. Solutions for car shake and vibration while driving include: 1. Clean the fuel system and check the idle control valve for carbon buildup, clean if necessary; 2. Inspect or replace spark plugs; 3. Replace brake discs promptly; 4. Check fuel pressure and replace faulty components; 5. Inspect the engine to identify problematic parts; 6. Clean the fuel filter.

Last time on the highway, I also experienced severe steering wheel shaking, and it turned out to be improper wheel balancing. If it shakes at low speeds, it might be time to replace the spark plugs or there's too much carbon buildup in the throttle body. I remember once in traffic, the car was jerking, and the mechanic said the engine mounts were worn out—the cracked rubber couldn't absorb the vibrations anymore. Tire issues are the most common—uneven tire pressure, deformed rims, or bulging tires can all cause the car to shake. It's best to check these first. Don’t underestimate such shaking; delaying repairs might damage the suspension system. Now, I always head straight to the repair shop whenever I notice anything unusual.

As a veteran driver with over 20 years of experience, let me tell you about car vibrations: If it shakes at high speeds, check tire balance and rim deformation; if it idles roughly, first inspect spark plugs and engine mounts; shaking during acceleration might indicate a driveshaft issue. Last week, my neighbor's car had severe low-speed vibrations, which were fixed by replacing an ignition coil. Actually, worn suspension bushings can also cause vibrations, especially noticeable when going over speed bumps. A simple self-check method: first verify tire pressure is normal, then listen for any abnormal engine noises. If unsure where the problem lies, the easiest solution is to drive to an auto repair shop for a computer diagnostic scan.

As a newbie, I was terrified when encountering car body vibrations, only to learn the common causes later. Tire issues are the most critical - even a 0.3 difference in tire pressure causes noticeable bumpiness. That time when sudden shaking occurred at 60 km/h, inspection revealed a deformed wheel rim. Broken engine mounts are also common - when rubber deteriorates, vibration damping fails. Once after car wash, I forgot to close the fuel cap, allowing air into the fuel line causing unstable supply, making the car jerk intermittently. Recommended first checks: tire condition, engine mount rubber, fuel cap seal. Don't be like me foolishly waiting half a month for repairs, which ultimately damaged the driveshaft.
