I got a slight problem with my benz. Everything works great when the engine is cold, but when accelerating she sputters. It seems that she's missing fuel or spark, there's no power to accerlerate but then on other times, it's just fine.

It only happens when you floor the pedal. You can drive just fine when accelerating slowly.

Engine starts fine cold or warm. The engine light is not on.

I replaced fuel filter, dist cap, rotor ignition coil, plug wires air and fuel filter, but no change.

Any suggestions would be greatly appreciated.

when does it sputter? all the time, only in D or R and then trying to accelerate? does it work itself out under load?

It does it when driving, at any speed/rev. It does not work itself out under load, she just does not want to go. But when you take the foot of the pedal, and accelerate gradually, not pedal to the floor, she'll drive just fine.

I'm not sure if it's also there whan in R, I never tried to go fast backwards. It wont do it whith little throttle.
