Ford Mondeo vibration

Car: Ford Mondeo
Variant: 1.8d Duratec model
Model Year: 2007
Categories: Running Rough, Starting & Power Loss
Hi all, have this Mondeo but very bad vibrations between 1300 rpm and 200 rpm at idling and when moving. Heavy vibration underfoot which gets very uncomfortable driving around, have replaced 3 out of the 4 fuel injectors but made no difference, it's a 10 year old car so don't want to spend too much any ideas?
It also vibrates a lot at speed-(120km +), I have replaced all tyres with new ones but still vibrates badly?
Appreciate any help before spending more !

Check engine mountings , check wheel balance .

Possible dual mass flywheel fault.

You have it as a 1.8d Duratec , all Duratec engines are petrol . Is yours a petrol or diesel ? If it does have a DMF , that will probably be your cause of vibration .

Thank you both for that. its a diesel engine with 111k miles on it, I was hoping it wasn't the dmf, I guess I'll have to get a mechanic to look at that. I'm also not sure if the fuel injectors were synced right, the engine can splutter at times and loses power for a second or two- my investigations
thanks again
