carbon deposit
Dear W201 friends,
Any comments for why my plugs gets carbon deposit that leads into a misfiring for about every 250-300 kms, then need some plug cleaning in order tomake a good engine run again, what so you think is the cause for having a carbon deposit on my apark plugs

Seems like the proper non-resistor plug. If all the plugs look crappy, then you can rule out individual suspects like the individual plug wires. Check the high tension lead to the distributor, check the cap, check the crankshaft position sensor and cabling.
If it's just one or two plugs, then it's something specific to those plugs.
