First, just so we're on the same page, it would be good to see the specific codes.
I noticed so far all cylinder #s are on the same bank.
I like numbers so would use a scan tool showing live data and look at the long term fuel trims, but also I don't know what basic things you have checked so far for example oil looks good, coolant too and no bubbling out the reservoir? Cylinder compression check is something else to consider. How many miles on it?
I agree with prior posts that depending on miles and/or years since last change, all new spark plugs and wires may be due, as well as a fuel pressure check, and before diving into deeper waters, run some fuel injector cleaner through it and if not driveable/much, double up the fuel injector cleaner ratio to get more through the system for now.
Ultimately after the basics it is time to hook up a scan tool capable of live data and look at everything.
