Not sure on your car, Does it have a dist cap and rotor? I had sort of a prob like this on my E420 and found that I had bad caps and rotors. Was told by a very good source that if the computer detects a misfire it will cut out the ign on on half the cyls to protect the cats. I replaced both caps and rotors and put in a new set of plugs and BigBlue has been purring like a kitten!!
