I have a 2018 defender which goes into limp mode as soon as it starts up. It throws a misfire code. P0301. I have replaced plugs. Wires, ignition coil, fuel pump, cleaned fuel tank, changed out map sensor, o2 sensor, throttle body, foot pedal sensor, pulled intake manifold and resealed it, replace after market full exhaust, checked compression which is 150 both cylinders, replaced injectors, cleaned grounds, and still goes into limp mode.im about to change the harness , but before I do I want to see if anyone else has any ideas
