2017 M3 idling trouble

[Hondastand]

My 2017 M3 is still idling rough. I've swapped the fuel pump, cleaned the tank, and added fresh gas, but no fix, and there's only 600 miles on it, is there any trick to removing spark plug wires without pulling the air box?

It's tough yeah but doable, you can get the spark plug wires out without pulling the air box using a long pick or plug wire tool, but its a tight squeeze and kind of a pain. Have you tried just removing the air box? It's quick and makes the whole job way easier and safer

I think you could remove the spark plug wires without pulling the airbox, but it's tight, I hope you have small hands and a bit of patience, try wiggling your way under the box with a long flathead or pick tool to gently lift the coil connector tabs

Using a long, thin pick or a special spark plug wire puller can help grip the boot better or better still temporarily loosen the airbox
