Hi guys I'm back again.
I have replaced numerous different items now. Including injectors, brand new cold start relay, to no avail.
But I have made some big improvement when I disassembled the mixture control unit and the fuel distributor and cleaned everything real good. The car runs and starts much better. The A/F ratio is set as well and holding.
On other CIS systems there is an initial throttle plate opening specification. At least the manuals tell you what the gap needs to be and one adjusts that by the set screw at the throttle stop. I know that the 300 E has a setscrew as well but the shop manuals do not mention what the setting is.
I guess I could go to the dealer and measure one but I find more intellect about MB's at this forum than anywhere else.

Does anybody know what the gap needs to be? Thanks for all.
