Suspecting injector issue.
EDIT: I would swap #3 injector with some other and check if it moves to different cylinder.

I don't know if KTS lets you to choose injector class but worth checking if coded class is the same as injectors installed.

The answer to the question is No! I have not, perhaps I should have but the misfire, injector behaviour is erratic. I don't believe Injector coding could cause such a Violent Misfire one minute and work fine the next. I will check coding before I buy any Injectors just to be certain.

My Position is that the Engine Starts on the Key and Runs and produced an Invoice for that work. Payment of that Invoice must come before I purchase any parts, Solve the Misfire, Fix the Brakes, the DPF DTC Issues, some Hexidecimal Calculations, EEprom work so it shows 90k and not 185k.
This is life !
but electronic timing wont correlate
