How to Solve the Body Vibration of the Eighth Generation Accord?

If there are issues with the operation of the spark plugs, high-voltage wires, and ignition coils, leading to poor ignition system performance, check if the spark plugs have excessive carbon buildup and replace them if necessary. Abnormal fuel pump pressure or incorrect readings from the intake pressure sensor can cause engine vibration. In such cases, check the fuel pressure and replace components if necessary.
As a veteran auto mechanic, I've fixed countless 8th-gen Accord vibration issues. The most common culprit is worn engine mounts - those rubber components crumble to pieces over time, causing the engine to directly contact the frame. No wonder it vibrates! If it's especially noticeable during cold starts, that's almost certainly the problem. Don't overlook these three other possibilities: First, spark plugs overdue for replacement cause unstable ignition making the whole car shake. Second, inspect ignition wires for cracks that cause electrical leakage. Third, check vacuum lines - older models are notorious for leaks making idle vibration feel like a massage chair. If all these check out, you'll need to scan the ECU data stream - some sensor might be acting up.
As a female driver, what I fear most is shaking. My Accord used to vibrate so much at red lights that my hands would go numb. Later, I found out there were mainly two issues: shaking during braking was due to warped brake discs, which required resurfacing or replacement; shaking in the steering wheel at high speeds was mostly a tire problem, often caused by unbalanced weights after a tire repair. Another hidden issue was a faulty CV joint, which made clicking noises when turning. Once, after refueling, the car shook violently, and the mechanic said it was due to water-contaminated fuel—draining the tank and refueling fixed it. Now, I have the mechanic check the engine mounts every six months, as they wear out easily in older cars.
Budget-friendly repair solution: First, spend thirty bucks to replace the spark plugs. If that doesn't work, check the ignition coils by disconnecting them one by one and listening for changes in the engine sound. During maintenance, ask the mechanic to check the engine mounts—if they're soft and saggy, they must be replaced. A clogged air filter can also cause the engine to struggle and shake, and replacing it yourself is super easy. Don't ignore the tires! Last time, my car shook badly, and it turned out the tire pressure was uneven—filling them up fixed it immediately. The final trick is cleaning the throttle body. If carbon buildup causes it to stick, spraying carburetor cleaner after removing it can keep it running smoothly for half a year. For an older car, keeping up with these basic maintenance tasks usually prevents major issues.
