Throttle pedal vibration

[zwoemba]

Hey guys,

My 197 was in for a exhaust manifold replacement, but since it got back I have a quite heavy vibration in the throttle pedal from around 3000 to 5000 rpm. Any idea what might cause this?

Did it have a new lower mount put it?

Hmm, not sure what you mean with lower mount...? There were a few things replaced though:

- exhaust manifold
- all engine mounts
- lower ball joint
- new front shocks

Sorry, didn't check what I wrote!

The new engine mounts will be causing the vibration. Give them a few hundred miles to bed in and you should be fine.

 

[zwoemba]

ok, thanks for the advice!

For future reference

I've recently mounted an upgraded torque link and the vibration in the throttle became even worse. I've thought I had changed all engine mounts by now, but seems there's also one near the timing belt. Guess what mount caused the vibration...

And on a side note, this is the new torque link:



What an massive improvement!!

may also be tracking.

Removing the silly trumpet next to the motor will also result in more vibrations below 4000rpm, but in a good way!
