9-5 Aero, slight stutter on tickover

[2013BRM]

Had this appear recently, seems worse when warm, am I looking at a replacement DI Cassette?

Try replacing spark plugs first - You would normally need to replace these when replacing the Cassette.

It may be the cassette - Mine packed up and cost approx £275 for an OEM part but takes 2 mins to fit.

Hope this is of help :-)

CPS is a consumable and most affected when warm.
