there is probably a missfire could be caused by multiple things, wires, plugs, coil, injector or related wiring. You need to get it on a scanner and see which cylinder is missfiring then swap one component at a time to see if the miss moves to a different cylinder. Then you will know if it's plug, wire, coil or injector.
