Hi guys,

My car is a 190E 2.5-16.

The engine was fully rebuilt about 6 months ago.

My main concern is that when you start it, it really shakes quite a bit. Engine mounts are new by the way. Also there is a hesitation in acceleration.

Now, i removed the fuel distributor and it was completely wet underneath and there was fuel on top of the air flow sensor body also.

I need to know, what are the symptoms of a failing:

1. Fuel distributor
2. Air flow sensor
3. EHA valve

By the way im getting really crappy gas mileage. C/O mixture has been checked, everything else on the car is 100%. New Injectors, fuel pumps, fuel pump relay, fuel filter, cold start valve, idle air control valve, intake boot housing that goes underneath the air flow sensor...all new.

I have heard of some guy called Pascal who rebuilds fuel distributors. Anyone heard of him? If so, is he any good?
What do they do when they rebuild it?

Sorry for the long post. Looking forward to the replies.
