Why does my BMW shudder when I accelerate from a dead stop or a roll-on below 5 mph?

My 1998 BMW 328i shudders slightly when I accelerate from a dead stop or when I accelerate from a roll below 5 mph. The shuddering starts at around 5 mph and between 1700 and 2200 rpm. The shuddering feels as if it is coming from the rear passenger wheel and it abates once I've passed 10 mph.|||could it be a faulty spark plug ,wire in a dark place open engine compartment to see if you can see arching between spark plug wires
