Throttle cable adjustment
 

I've narrowed my two year battle with limp home down to the throttle cable adjustment. The car is a '93 300CE with the 3.2 engine. Alldata shows a completely different set up than I have. I realize this car was in between models but I was hoping for a better diagram. I have seen specs for TWO different clearances, one at 1/4 inch and the other for a lot smaller value in mm's.
We found out that if it is too tight, then it is in limp home continuously. There must be a spec to help.
Anyone?
