I have a W124 E220 1996, it has a problem, when you take your foot off the accelerator the thing cuts out, so you have to keep the revs on all the time. My mechanic has checked the fuel relay and the fuel return pipe- but still no joy, any suggestions on what it is, and does anyone know of a W124 Mechanic in the Leeds area (excluding Merc Care please).
 
Clean the throttle body throat and throttle butterfly carefully with solvent. it get crudded up with oil and sticks.

And if this doesn't work I would suspect wiring loom problems
 
These also suffer from the electronic throttle body failing, which can cause the symptoms you mention
 
I went to see scotts autotec close to the centre of Leeds last Monday with my W124, they were very accomodating in taking a quick look at the car at short notice (I'm not based up North and concerned about the journey back). They seem to get good writeups across the forums and certainly knowledgable enough on a w124.
