yes 99% sure it is mate, feels like a really light wheel imbalance, more obvious if you put you have on the front fender at idlephoenix wrote:Can you describe the shimmy/vibration in greater detail? If you hold the revs steady at say 2,000 rpm is it constant?
Nylon rope trick gone wrong

Are you sure all cylinders are firing? Maybe pull the lead off the cylinder that you put the rope down (with insulated pliers!) whilst running, see whether the rpm changes with it on or off.

good question, have checked and everything is attached correctly, tried disconnecting some plugs to make sure and everything is good, also sounds perfect at idle.RS13 wrote:Are you sure all cylinders are firing?

I'd check the engine/trans mounts next - I read something a while ago about 1UZ mounts being susceptible to cracking.
The timing is bang on? Have you run diagnostics?

Swapped out the harmonic balancer (over-fortnight parts from japan) and it seems to have done the trick. The old one took a bit of a beating.
Had a few runs up hill at full noise and revs and it's absolutely fine, phew.
So, in summary - never doing that again.

Through Mark? I didn't know you were looking for a substitute - I have a working condition one here
