Possible causes for code P0300 you've already change coil and plug.... P0300 could be bad #3 plug or coil... switch those also and see if code change.. if it persist try the next thing.. I would try trading fuel injector 4 to 5 and putting 5 into 4 and see which code you get..... Faulty spark plug (s) Faulty ignition coil (s) Clogged or faulty fuel injector (s) Intake air leak Fuel injectors harness is open or shorted Fuel Injectors circuit poor electrical connection Ignition coils harness is open or shorted Ignition coils circuit poor electrical connection Insufficient cylinders compression Incorrect fuel pressure code P0305 is simmilar.... Faulty spark plug 5 Clogged or faulty fuel injector 5 Faulty ignition coil 5 Fuel injector 5 harness is open or shorted Fuel injector 5 circuit poor electrical connection Ignition coil 5 harness is open or shorted Ignition coil 5 circuit poor electrical connection Insufficient cylinder 5 compression Incorrect fuel pressure Intake air leak
