Hi everyone and Happy New year. Has anyone ever had a shuddering or vibration about 1800 to 2000 revs which dissappears soon after or you can power straight through it. I`ve had wheels balanced firstly so its not wheel related

Many...
If you'll enter the word "vibration" in the forum's search engine, you'll get many hits.

Hi and welcome to the vibrators owners club ... there are quite a few of us suffering from this horrible problem and many of us have tried many many things to find the cause with no significant result . I recently bought a set of electronic listening equipment to clip onto various components with the hope of picking up the vibration and after hours messing with it no result.. I swapped the nearside front driveshaft last week as had a lot of up and down movement ... no differece so tomorrow I’m fitting a new crank sensor and also a new serpentine belt tensioner just to eliminate them really oh and also looking at the condition of the drivers side hydraulic engine mount . Had my mot last week and even with all his years experience found no play anywhere in drivetrain etc . Please share anything you find .tim

Ok update today I changed serpentine belt tensioner and crank sensor also removed right side engine mount no signs of wear or deterioration and this once again has made no difference to the vibes . Seems to affect early autos more than others maybe a bad batch of something eh. Really like my FL but this really does spoil a great car .
