Hi,

You say no codes are set!

So we are into guesses.

Bad Fuel? Try using up the old and get some new in from a different source.

Crank Position Sensor? These give problems and are easy to replace but usually give NO START rather than low idle.

It could be 101 things so I won't just give you a long list.

Any further clues. Current mileage, service history, when did it start, does car run OK otherwise etc?

Did you go to a main MB dealer with Star Diagnostics or some independent garage somewhere without the appropriate diagnostics kit?

94 and 95 E's were notorious for bad engine harnesses, inspect them at airmass and at injectors. actually really anywhere you will see that the insulation on the engine harness is cracking and brittle and it exposes the metal wires and then you'll have all sorts of troubles. if this has not been replaced that is the first thing to repair before doing anything else.
