hello ladies and gents.. I have seemed to have found the root of my problem.. the plug caps! the cyl shaped apparatus on the end of the spark plug wire that connects to the spark plug.. I used electronic component cleaner and cleaned them all thorougly.. the car misses no more and hesitates rarely I have all but forgotten it had a problem at times..thanks to the thread from forum user/560 guru thomas godley who has owned several 560 engined mercedes and wihtout him I would have been little more than guessing what the problem might be.. in short he stated that all of his 560 engined cars has the same problem at one time or another..and these caps were always the culprit.. Ill get new wires and caps and report back as to the results .. I am very optimistic that they will solve my problem.. the chk engine lite comes on and stays on for approx 3 min every other day.. but I think thats because unburned fuel is getting into the exhaust.. my gas milage is not the best at the moment either..again I think new wires/plugs will solve the problem

Thanks
Demeterial :p
