Slight stutter

[Sha83]

Hi all

I git a clc 220 cdi automatic when I’m driving the car jerks stutter slightly feels like something not getting something, I’ve changed

Fuel filter
Oil filter
Oil
Egr valvue
Air filter
Transmission fluid

Also added cataclener

I’m still have a slight stutter

I’ve put the car on diagnostic and no errors have come

Only think I can think of us fuel injectors

Anyone else got any thoughts ???

I also have a slight stutter when cold, injector or fuel pump I recon,

Noticed a bit of black smoke from exhaust when I revd 4000rpm, not sure if anyone can advise me any further

Hope it’s not the fuel pump, pumps inside the fuel tank I believe
