Recently obtained a 5-speed 2001 with 32K miles. Had terrible engine vibration so I took it in to the dealership. Three engine mounts were broken which they replaced and called it done. Of course the engine vibration was still there so I escalated the issue and turns out all valves were to tight and that was causing the vibration. The valve adjustment has helped - lots, but the engine vibration is still there. I have cleaned the EGR, replaced serpentine belt, check spark plugs, done all fluids etc. but still the vibration. Most noticeable when it's cold (very noisy and rocks the body of the car) and very noticeable when shifting out of 1st gear. Around 3000rpm under load, just letting out the clutch results in a wa-wa-wa vibration you can feel in the whole car as the engine rpms come down. Shifting through this vibration makes for a rough herky-jerky shift. Honda dealers tell me this is normal operation and they cannot detect any abnormal vibration. Any ideas on what I should do next?
