This sounds very similar to the problem I was having with my 2.3
What happened originally was the engine was replaced, and whoever was getting it to run, did not know that older models of a 190 have different amperage in the EHA then the newer models since 86 I believe.
So my car was set for 0mA in the EHA, which caused it to actually run really lean, and as a result the car hesitated like no tomorrow, but was driveable.
After testing and testing and learning all the thories of the engine, all it took to correct the engine was a slight turn of the air/fuel mixture on top of the Fuel distributor and the car was running like new ever since.
One thing does leave me worried however, on the beginning, azhari metnioned that he got 450km out of the car before the fuel light came on. I can only get 450km out of the car from pure highway driving, on the streets I get up to 350 and although I never let the fuel light go on, I have to pump up to 45L of gas to fill up, and according to the manaul, I only have a 40L fuel tank.
Now what I would like to find out is why my car would not start when I had the mixture set right on 8mA. I had to richen it to get it to start, with the correct mixture setting it would not start. Can anyone think of anything?
This is cold or warm starts, but mostly warm if I remember correctly.
I would really love to be able to get 450km out of my car on regular streets and not just pure highway driving.
And it also looks like I have about 11 months to do this before my final emissions test which I would like to pass without any problems
