Success! Went out about an hour ago and changed the plugs to AL104's. Carefully did the front bank plugs first then made my way to the rear and was even more careful. #6 cylinder tried me again getting in the new plug but i found myself an easier way to get the plug in without too much hassle. Fired up the car let it run for a few minutes,revved no misfire. Then went for a drive starting off easy then part-full throttle and no misfire! Car seems to feel healthier now,thanks for all the help guys.
