vibration under 2000rpms

recharged95 · 11-08-2002, 08:22 AM

Hi,

I'm starting to get a very noticible driveline (via shifter) vibration under 1800 rpms+under load. If I freely rev the engine in netural at 1200/1500rpms, etc.. there's hardly any vibration. Could this condition be caused by a defective harmonic damper (just replaced in June)? Or a bad spark plug?

thanks,
Cliff

Hi Cliff, I would check your motor mounts to see if they've come apart, that exactly what mine was doing, and it was the motor mounts, hope this helps, Kenny
