You must mean red COIL . not dist.
The red coil and 1/8 Ballast are a comon upgrade and will not cause your misfire.
The 5 k and 1 K are b/c of the right angle connector. many guys worry about it , but it should not cause a misfire. There are a hundred stories of why Benz did this , and I believe that they just did not have any 1K right angle connectors available.
Anyway, those are solid wires , so I would start with a compression test ..if that is off , I would do a leak down test. [Check for tight valve adjustment]
Do you have a scope? That is what I use , but you may not have one, so..........
If misfire is ign related, as said by others ..look at the cap, both inside the wire terminal and inside the cap for tracking. I would also try that one with another connector. Just b/c a connector ohms out does not mean it does not break down at firing voltages.
You may also have a bad valve seal , allowing oil fouling.
What does the read on the plug indicate?
