Have a 10 Audi A5. It keeps throwing a p0030 code misfire on cylinder 4. Did have the piston and rings replace for the oil consumption, replaced the coils plugs and the fuel injector on the cylinder. Just replace the pcv and still nothing and has rough idle. Any help would be appreciated.

I thought this code was something to do with a failing 02 sensor
