2013 X5 35i Random misfire problems. P0300

[bojan2512]

Hello everyone

OK so the car had a little hesitation in the morning so I decided to change the plugs thinking maybe it will stop the hesitation. It ran perfectly after the first start up it was just a little hesitation in the morning just a little bit. So I purchased new plugs from FCP euro and installed them. The car started miss firing on cylinder 6. Then I would reset the codes and the car would start miss firing on different cylinders. Then I decided to put the old plug back so I can see if it will fix the problem. The car at this point was not drivable. I tried switching coils back-and-forth and that did not fix the problem. Then I put the new ones back in and at least at this point the car is drivable when I drive it very slow on the very little load. Now I have a random misfires under load. If I go past quarter throttle the car will start misfiring randomly. Code is P0300. The hesitation in the morning seems to be gone. If anyone had a problem like this please help I don’t you can I don’t know what to do at this point. Thank you!
