w208CLK 2.3K RPM fluctuating on cold

[jtang7]

Hello forum viewers.
3 weeks ago I bought a 2000 CLK 2.3 petrol 111.000miles and on the first time I started the car on cold with the gear on P it had some trouble in maintaining the rpm. I would guess was because it was cold and after like 30s with the rpm going up and down the engine died. No problem in starting again but then driving and stoping the engine keep jumping the rpm.
Happened second time but after car was warm no problem.
This night even when the car was at normal working temperature when i stop the car and i leave it on D the rpm was fluctuating and engine shuts. No problem in starting so i decided to test the accelaration of it and pressing full throttle didnt respond sometimes with the normal fast accelaration.

Any advices?? Thanks a million!!!!

fluctuating revs

Hi again, has it got good service history, has the fuel filter been changed,if this is full of gunge / water it will give you the same effect! until all the basics have been checked / serviced, its a needle in a haystack! if all is good then you can move on to technical theories etc!
