Hi Guys

I have caprice WN 2015 6.0 which has done 80k and I need your assistance engine is running rough and misfires I did diagnostic on the engine and it come up with P0300-00 I changed ignition coils, spark plugs and ignition leads and car is still running rough but what's confusing some times it runs fine and suddenly it starts running rough. Any ideas??

Could be injectors? Not much left besides MAF sensor after all the work you've done, maybe you have copped a bad load of fuel and now have some cranky injectors
