If it's doing it at idle I'd suggest coilpacks!

This but I'd do a vcds log scan for misfires before fiddling with changing coilpacks...

Did you log misfire count with the engine running or just did a standard fault scan?

Sorry a bit off topic, do you still have the UB spacers for sale?

I have an R32 and was running a blueflame cat back and all was
OK but I have fitted a Milltek cat back at the weekend and now the exhaust is fouling on the UB.

Can be contacted on following email

If you use vcds then a live run logging blocks 015 and 016 will show up which cylinder is misfiring. You only get a fault stored if the misfire count exceed a certain value.
