Engine stumble

I have a E320 1994 104 engine. The problem is that when I take off from standing still the cars stumble almost stops 1-2 seconds then it take off and when I accelerate the car misfire (don't now if is the right word).

No problem when cruising in same speed and accelerate slowly.

No codes. New wiring harness, plugs, fuel pumps fuel filter,ignitions cables,Spark Plug Connector, I my self suspect the ignition coils but no codes.
Could it be fuel related?

Very Good

You guys are getting hip...

Try cleaning the MAF and see what happens ..don't touch the film inside ..just spray it good and let it dry.
Then , after maf install, go back to pin 8 with the led tool and clear until you get a single flash back...[ meaning no code]..then wait 2 secs after single flash, hold button for 6/7 secs , turn key off for 10 secs , On for 10, then start car..that will bring base line memory back to zero for adaptation.
Drive car a couple of days for adaptation and then go into 8 again for a check... you mat need a Maf , but sometimes this works if they are dirty from a bad air filter.
That CRC MaF stuff is good..
