2005 5.4 trouble!!!

So my friends 2005 f-150 5.4 3v with 114000 miles truck took a dump today. I don't know the full story but I put the edge on it and got the codes it threw.

As he said it, it was misfirimg like a bitch. His left side converter was bright red. Truck was shaking bad and had no power. Couldn't go much faster than 45-50 mph.

For some reason when I pluged in my edge it kept saying DCT Alert 7

The codes that I got are...
P0300 random misfire
p0305 and p0308 misfire on 5 and 8
p0316 misfire on startup within 1000 revs.
P0175 system too rich bank 2
p2198 sensor signal biased/stick rich bank 2 sensor 1.

I don't have a clue I'm hoping you guys can help out. He's trying to avoid the stealership!

Thanks guys!

Sounds like to me is that it might be one of a few things ,first you might have one or more coils going bad which would indicate a misfire, or one or more fuel injectors are startong to crap out .The red converter could be from a rich mixture caused from misfiring coil or coils, I would start with coil and plugs

That converter is plugged up.Exhaust restrictions can cause all kinds of issues.I agree that there is likely more than just that causing the problem.

Did your friend ever replace spark plugs? I don't know for sure, but I would say whether the converter is pluged or not it's probably toast. How come there are two converters? Can we go with duel converters legally?
