1992 300te 4matic with 186K...
Recently I have had two problems (no snickering from the anti-4matic set,lol)

1.my gas gauge will flutter if i am below 1/2 tank

2.the car will sputter/surge if i am low on fuel (ie when my yellow low fuel light comes on)....today was the worse where the car would basically shut of if i came to a stop.
The problem cleared up after i filled up the tank.

Any help appreciated even from the anti-4matic set.
