Did some testing and measuring and KL15 seems to be missing. took some jumpercables to try and its still running bad after but could be my ignition coils and or also spark plugs being bad

Open engine wiring harness. Find where is the open circuit. Repair it and inspect other wires in the harness. They may be damaged as well. Wire isolation cracked for example. Continue with engine diagnostic only after engine wiring harness will be inspected and fixed and insulated with proper materials. Or replace complete engine wiring harness.
