Cold start startup rough
2014 BMW X5 50i n63tu replaced coils, plugs 1 step colder ngk iridium, replaced both hpfp less than 1,000 miles. Noticed lately my cold start runs a little rough and I hear a slight wouldn’t call it a whistle but air blowing or sucking for a second or two. Idles a little off during it the cold start. And if I drive it after there seems to be a very low rpm stutter almost like a hesitation. Anyone have any ideas???

I’m gonna see if any local shops do a smoke test so I can figure this out. Also very low rpms I get a rattle/metal sound from the drivers side that I also noticed, any idea?

I also had some low speed shudder because of the Tcase. Dealer blamed my 22s but a fluid change got rid of it. |
