First, the o2 responds to a snap throttle but only ranges from 300-700 mv. At idle, it slowly switches from 300-700 mv. Bank 1 sensor looks normal. I'd say it needs a sensor and is unrelated to the misfires.
I can feel a multiple cylinder miss at cold and hot idle. It also misses on throttle tip in. (In neutral, I did not drive it)
So, all that to say that BBB now sucks and doesn't have an Ignition or Injector wiring diagram for any Ford V10.
Can someone post the coil and injector diagrams for me please? Thanks

Going for the low hanging fruit, I'd chase the tip-in misfire first. A primary ignition waveform from the coils will expose any weak coils/plugs. Once you gather enough evidence for more than one ignition problem, it's easier to build a case for replacing all coils and plugs.
The rich code is weird. :huh: And it doesn't explain the P0303. I'd be interested to see what a VE test says at WOT.

WHOA WHOA WHOA YOU ADDED A P0316?!?!
Kidding! :silly: You're certain to find a bad coil or two now.

All coils check good at 0.6 ohms. But this shows coil 6 is dead. Trigger on coil 1
Coil 3
This was an easy one but it still feels good to collect this kind of dada for a DIYer

It really doesn't have the miles to necessarily need all the coils either.
I guess it depends what they want to spend on the van.
I wouldn't be ashamed to do just the failing coils, all the spark plugs and just a good visual of all the coil boots while you're in there. The plug wells collect crap like it's their job so I like putting a squirt of dielectric grease in the boots during assembly.

Every time. I used to sell individual plugs/coils, but got real tired of the "comebacks" when a different one would fail. Now they all get a set Motorcraft plugs and Denso or Motorcraft coils.

But it can still be a pain to get at the coil hold down bolts. Especially if the heads are rusty and swelled. In that case, definitely pull the rails and beat a sacrifical 7mm socket on.
