have u checked u aint just hit someone and there head in wedged in between ur wheel and shell ?
an intersting topic
i have the same problem, i think, well its sounds the same ish
i have bothered with it, it has been like it since the day i got it,
it passed an MOT fine
if you do think it may be a misfire and you dont have a spark plug socket, get some good insulated gloves
just pull each ht lead off,
if you do have a misfire at what ever cylinder it is at, when you pull the ht lead off the engine wont change what so ever,
obviously if you pull a ht lead of a spark plug that is firing it will obviously start missing on that cylinder making then engine shake and engine note to change
hope this helps
