focus 1.8 tdci 115 hp 111,000 miles.
engine idles smoothly, but it produces a lot of vibration only at 1200 rpm, beyond this it runs steady and smooth. fuel consumption ok 50-55 mpg, no smoke, plenty of power. replacing clutch soon as DMF in knocking and clunking, could this be the cause of the vibration. Its done this since ive had the car thought it was a engine characteristic, is it?
Thanks
have you tried removing fan belt to see if the vibration is still there?If you are replacing your clutch and DMF that would rule those items out,if the vibration is still there then the timing belt/tensioner may need looked at.Not sure on this model but some crank pulleys have vibration dampeners built in to them and may be worth a look also,good luck.
