Idle jump up and down - 156 2.0 TS

Seems like I have to drive my Alfa Romeo over winter this year but I want my idle fixed first.. no engine light but if I drive slowly using clutch rev start to jump up and down, even if car go quite "smooth". If I drive away instantly after I start it will it drop all power for a sec then get it back since I automaticly clutch and give little more gas

Driving smooth, maybe make a small cough per 30-45min
Also when I stopp for a light or sign idle jump up and down ~800 to 600 or something. The Variator makes a bit of a noice but its gonna hold untill timing belt change unless.

I dont think a bad variator can cause this type of problem (Dont sound THAT much of a diesel like those examples on youtube does, If its an complete engine failuer do I have warranty on it :3) But may it be the gasdamp/throttlehouse or what to call it? Or leaking coldstart injector or one injector in general..

clean your throttle body out off black muck ,,whilst pipe is off check for splits in that and refit and tighten all fittings
