Random misfire E420
So i have a misfire in my 420. The car runs and drives perfect when up to speed on the road, but when i come to a stop, it skips pretty bad, sometimes even surging. It also starts real rough when cold. So far i've replaced; Plugs, wires, distributors, and rotors. Also, i have inspected my wire harness and its in good condition. Could this be a problem with one of my coils? Any help is appreciated

Probably not, but it may need doing anyway. I found that when my therm was bad my car ran much much nicer. It was running on the warmup mix constantly as the engine never got over 80C or so :P
Gimme the stats on your plugs sir, I am suspecting them.

i know what your gunna say about my bosch plugs 
lol. But honestly, we use bosch plugs daily at my shop and we have never had a problem with them. Ignition wires are another story...
Im suspecting a coil that could be on its way out because the car runs perfect when rpms are over 1200.

they are long gone, i threw all the old boxes out and have since made a dump run 
I will have to pull one out. But if it was the plugs it would have more of a constant skip even at higher rpms.
