The plugs fouling indicates too much fuel is being injected and this would cause erratic running. The engine not revving motre than 2000 rpm and the extra fuel indicates you most likely have a fault with the throttle body. You should try reverting to the original components and see which conomponent solves the problem, starting with the one easiest to replace.
