I need help. I did a complete spark plug and coil swap on my 2016 m235. Sitting at about 103k miles. This was done in prevent and the car ran perfect prior.
Now, I am having a misfire on cylinder 2 and the idle is atrocious. I have swapped coils, the misfire doesn't follow. I swapped the new plugs back to old, same cyl 2 code and the idle is even worse.
I truly have no clue what to do at this point and don't really understand how the car is now running like a bag of shit after it being perfect this morning.
Please help me figure this out.

Check the pins in the connector, maybe one bent

Checked ‘em all, no avail. I unfortunately ended up having to take it to a shop. Hoping to hear something positive today. Thanks for replying

I highly doubt it's anything serious. My guess is the insulators are cracked on two of the plugs, the gaps are wrong (should always stick to stock gaps in almost all cases), or these are knock-off plugs . Did you remove all the crap that was in your way to get to cylinder #2 or did you snake the plug in? Where did you buy the plugs from? Gaps checked?
