Mileage?
Service history / recent work?
You say you've replaced parts - what were they (ie, is it possible you've disturbed something during the work you've done?)?
You say you pulled the plug leads off - the cylinder you disconnected must have been firing properly (hence why it ran even worse after; if it were faulty, pulling that lead off would make no difference). Have you tried the same with the remaining leads (or, indeed, have you one downpipe cooler than the rest?)?
