Looking for some help!

My 2000 e36 318ti failed its test today on a couple bits but the main thing was the emissions.
I have noticed it has a rough idle and jumps above the 1k mark almost like a misfire but I’m not getting any lights on the dash.
I’ve changed the spark plugs to some new NGKs but it’s made no difference.
New exhaust with a cat has been put on.

I’ll attach a copy of the emissions if that can help get to the bottom of it.
thanks!
