Hi Darren,

Is it vibrating at a certain rpm when stationary and on the move?

During the cambelt change the engine mount is removed so a check of all those fasteners would be a good idea.

The driver's side wheel would have been removd so I would double check the studs on that as well.

Any other information you have may help such as,

Is it vibrating at a certain rpm when stationary and on the move?
Is the vibration at a certain car velocity or completley rpm related?
Is the vibration coming through the steering wheel?

I have a vibration on mine if I put my foot down hard between 1000-1500 rpm, I think its the top mount but haven't investigated it yet

I didn't realise until I re-read it that it was a 2.1, they are normally very smooth so unless its misfiring I would be inclined to check the crankshaft pulley.

Possibly an out of spec injector?
A Lexia session should identify it if that is the problem.

When you did the cambelt did you lock the flywheel, camshaft pulley and pump pulley with screws?
