Misfire #3

[Ziyadh X5 50i]

Hi Guys,

I’ve been having a persistent misfire on #3 on my X5 50i N63. I have changed the plugs, coil pack and injectors all OEM parts. Injector was coded as well. Car starts up fine drives fine then goes into limp on wot. Anyone with similar or same issue?

Firstly an introduction would go along way.
Secondly check the 02 sensors, or have the car scanned for any codes

Excuse my rudeness, I’m Ziyadh, have 2 bmtroubleus but will never change it for anything. BMW X5 50i M sport and Bmw 135i n54.

So the only code I get is cylinder 3 combustion misfire P0300. After picking up the malfunction reduce power warning. I cleared error drove it like I stole it. Car went well. Then next morning it came up again. I Replaced coil,plug and injector, coded injector cleared all faults and it’s still comes back on wot.

Check 02 Sensor bud !

Maybe swop over plugs, coils and injectors and see if the misfire moves or not
