Hey team
Was hoping to get some technical help as I'm at my wits end fixing the missus' 500x 1.4L mutliair turbo from 2017.
RHD. FWD 103kw model.
The dealership are fully booked out for another month (!) and my mechanic is on leave so I thought to try do some of it myself (coming from someone who used to self-service all Japanese cars).
Recently has had problems with stalling, rough idling and misfiring. Started off with cylinder 3.
Running a mobile phone code scanner:

I've changed all the spark plugs to NGK sparkplugs, swapped the coils around. Even pulled out each ignition coil serially to see if it would make a change in the firing and it went really rough individually so I don't think it's any of the coils gone bad. I've reset the error codes to see if it'll spit out another error after changing the spark plugs but nothing popping up now despite the car stalling and being just as bad!
For what it's worth, the cylinder 3 spark plug was quite disgusting and had a lot of soot near on it.
When I rev it to 4000rpm and let it drop back down to idle, then this really exaggerates the problem. Currently it's really rough idling and half the time it'll stall when I'm idling. And it's a struggle to restart it, on occasion it'll not turn over, just splutter for a bit before stalling. It'll take 2-3 attempts to turn it off.
I'm at my wits end what to do and I don't really want to fire the parts cannon anymore unless someone has some idea?
Thank you in advance.
