Hi You need to get the ecu checked for fault codes if there are none it is possibly low fuel pressure you should allso check this have you changed the fuel filter or opened any fuel lines this could introduce air
which will lower fuel pressure.Good luck Chris.

I had a similar problem with my 1986 300e , which got progressively worse until the car was no longer driveable, I changed out the fuel pump relay and the problem went away.

If the ecu is under the battery tray(plastic unboltable), remove the tray and check for contamination around the plugs. commonish fault with the 1.9
