Default What is cylinder voltage?

Anyone clue me in on what cylinder voltage measures on vag? I'm getting random misfires on cylinders 4 and 6. If I clear the codes, I get them right back on start up. Minimal misfire but I can feel it at idle or holding steady moderate throttle. Started watching cylinder voltage and misfires and that was showing cylinder 5 misfiring and the voltages were a bit lower on cylinders 1 and 6. 06 C6 3.2.

Thanks,
AJG

I think it is likely injector voltages.
Which group were you looking at and what DTCs are showing up ?

P0304, P0306, and P0300. Groups 16, 26, and 27 (in the link, 26 and 27 fall under knock control so I'm assuming it is the knock sensor voltage).

Those are generic codes, so I generally don't bother to look them up.

That was my other thought, and lacking coffee this morning, totally forgot to mention it
