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

[AdamLynn]

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.
