Poor acceleration on W202

[M Paul Lloyd]

Forgive me if this has been covered already but I'm a bit pushed for time right now.
I just wanted to share this incase it was of any use to anyone?
I had a problem with acceleration as in I started getting a flat spot as I depressed the accelerator pedal making my progress more Kangaroo like than smooth and serene. I thought it was the throttle linkage and indeed it may have been in part as a good clean and re-greasing seemed to cure the fault for a while, but it came back and has been getting steadily worse. I was beginning to lose faith until that is I noticed a small green plastic hose (see photo) had become detached just infront of the fuse box. No mention of this in the Haynes manual (why am I not surprised!?) A quick temporary repair has everything back to normal.

Thats part of the vacuum system.

That's excellent thanks, I guess my problem may have been with the "ENGINE VACUUM CONNECTION AND LIGHT RANGE REGULATOR" as the central locking etc are all ok??

Those are excellent diagrams by the way just a pity they are not colour coded.
