Seems to me almost all of those codes could be traced back to some kind of vacuum leak at the intake
What? Even the O2 sensor P0155?

I just happened to notice the the main harness was chewed on up on the firewall. It doesn't look like the wires were chewed through, but you can see where they are corroded. I was initially going to just coat them with a liquid electrical tape, but now I'm not sure what I should do about them.

Anyone know what that large green wire and white wire goes to before I pull up a diagram?

I also noticed this ground strap hanging loose, It comes down from the wiper motor to the engine block, but I'm not sure where it bolts to.

32026

I found a hole in the to of the exhaust manifold that was threaded, and tried putting the bolt in there, but it doesn't want to go down far enough.

I was going to suggest going through the harness, to me a lot of those sound related to a bad ground but I think you've found a few issues already.

My credo
In theory, theory and practice are the same. In practice, they are different.
You could try cleaner ng those skinned wires with contact cleaner and then coat with liquid tape. That would at least be an easy temporary fix while you try to pin down electrical issues. Definitely need to attach that ground wire somewhere.

Man, I DO NOT envy you OBDII guys...

Jam a paperclip in a harness, count flashing light blinks, unplug an ECM for a few minutes, run a can of seafoam, and POOF, all problems solved.

Seafoam. Hmmm.


Switching rates of the O2 sensors watching it live on the scan tool

I never looked at it after some run time. The intake and throttle body were caked from pvc and egr flow.... Was supposed to go through and clean the idle air bypass as well.

Vacuum and exhaust leaks can definitely set up most of these codes. Hard to see this many codes out of the blue. Does the harness damage seem engine swap related?

All of the under hood fusebox fuses are in place?

The harness was chewed on by a mouse.

Funny thing is that the truck seems to run fine.

I check all of the fuses. I don't recall seeing any missing, but I'll take a look.

Can someone with a 4.0 OHV tell me where the big ground wire at the wiper motor is attaching to their engine at?

I'll be ripping a 1995 apart this weekend. I'll see if that one is still attached.

Honeslty Jim I wouldnt worry about that ground wire as I would run a fresh new one from motor to the chassis and battery for the sake of testing right now. I never been a fan of those bare ground straps Ford used.

That ground wire is typically bolted to the backside of the head.

the braided straps reduce high frequency electrical noise better than stranded wire. (old super secret military knowledge)

I got the ground strap bolted to the back of the block, erased the codes, and drive the truck to confirm that the ground strap wasn't having an effect. The codes came back.

I replaced the DPFE with a new one...

20191009_153707.jpg


And replaced the O2 sensor.

20191009_141130.jpg


The O2 sensor takes a 22mm or 7/8-inch wrench. I actually had a 7/8-inch line wrench that worked perfectly. Your new O2 sensor should have some anti-seize on the threads. If not, make sure you add some.

I reset the codes again, and took it for a drive for a while.

This time when I got home their were no codes, but the CAT is still showing that it's not ready :dntknw:

Looks like I need to find the proper driving procedure that will make this ready to test. My 30 day plate expires on Sunday, so I really need to get this thing tested by Saturday.
