Have you only tried platinums? Platinum spark plugs suck, find just stock replacements.

these are the bosch platinum 4's and to my understanding one of the best plugs to buy for your beemer... and i have tryed stock replacements... they lasted less then a hour of attempted tuning... the 4's last almost 2 days'84 318i

ditch the platinums, get the stock copper plugs, and put in a new FPR.
see if that works.

when you pull your plugs out do they smell like gas? or are they oily? if they are black andoily, you are getting oil in your combustion chamber, which could be like a faulty PCV system or bad rings maybe. just get bosch coppers, not sure of the number on the top of my head.

ok my plugs are carboned over... do you all know what i mean by that...? theres no oil or anything else on them they are powdery and black... sooty even i believe it is caused by overheating of the fuel and combustion system due to a bad FI coolant temp sensor... but i was wondering if there is anything else that can cause that... if spark plugs is it then that great problem solved... but if the plugs i am using are fine. what else can cause this problem, if my engine checks for mechanical problems check out...'84 318i
