i know for a fact, that the last one has something to do with ECU power.
and i think the first 3 are cylinder misfires, NOW, what does that really mean? plugs? is it something dangerously important to take care of ASAP?
thanks,

Well cyl 1 and 6 are miss firing
that could be a lot of things, although they are on apposing banks. You may want to hook up a vag and see if you're still getting misfires. Also hows' your driving habits lots of short trips?

Humm it still should come up to temp.. not sure how deep you wanna get with this
but for starters I'd run some cheveron Techron Fuel system cleaner and take it for a nice long run. You may not be getting the plugs up to temp so they could clean themselves, but 20 minutes of "driving" should be enough. Anyway start with fuel system cleaner and a nice long drive, see if they reappear the next day on a cold start up, don't know the data block off the top of my head. If it's fine the next day and shortly after but comes back in a few weeks you may want to consider hotter plugs but they might cause pinging and other problems.

...the other DTC's you mentioned specifically tells you which cyl is misfiring as per the table below:

...could've been bad gas, no?
