Rough idle, and poor shifts at 4k?


i'm not sure if this has specifically been covered in a thread before, but on my 128i (N52N), the car seems to have a pretty rough idle. It likes to jump a fair bit within around a 500rpm range. Another thing I have noticed is the car doesn't like to shift at 4k, anything above or below is fine, just at 4K theres quite a bit of stutter (auto trans btw)

Any cause for this? the spark plugs and 2 ignition coils were replaced within 10k/km.
