Car feels like it's going to stall

[NW_Merc]

I have put my pre-facelift W202 to bed until next year while I do different mods i have been putting off. Anyway I have a facelift W202 which I am running around in and it has juddering symptoms almost like it's going to stall but doesnt.

Now 3 questions:
1. Could it be the Crank position sensor causing these symptoms? (My car hasnt actually stalled yet while in motion or while idling - touch wood)
2. Could it be the MAF?
3. Is it best to get it checked via STAR in order to see which sensor is the culprit?

Any help very much appreciated.

hi mate

1st call for me would be to check plugs and leads, that can cause those symptoms from experience (i cleaned the engine bay and moisture got in to the leads)

The car has been sat and not driven for about a year, maybe a little more than a year. Thanks, I'll check the leads. I think it needs an Italian tune up
