I have a1979 450SL V8 FI with a running proble. When I start the engine it runs fair for about a minute then the engine starts run rough. If you try to push accelerator any at all it will go dead.

I have replaced the plugs, cap, rotor, wires, and the fuel filter.

I have done all that I know to do. Maybe somebody has seen this type of problem before.
