Two threads on the Code 213 problem from the archives:

There is a PDF file clipped from the Ford service manual for how to check for an open circuit, short to ground, short to B+/VREF and assorted other items.
Some items of interest are make sure your ICM is black. Usually if it is gray you will get a loss of IDM code.

Section 8A in the manual refers to tests involving a Rotunda Ignition Analyzer. Obtaining one of those could be tough and probably expensive. Based on the posts in the threads I referenced the most likely causes are a bad PIP, ICM or computer. Probably not what you were looking for.

Went in the dumpster about 98' & the last guy who could use it quit in about 06'.

To update, I know why my 311 code is popping up. The 95 f150 4.9 e4od pcm that came factory had a different emissions setup with no air injection in the heads. The M/T pcm has four vacuum solenoids and air injection. I've got a spare distributor, thinking about putting that in and seeing if that fixes anything. Then again, if I'm going thru the trouble of replacing the distributor, I might as well and get a new motorcraft one.

When I was moving the wires around while the truck was running, it started running rough. I got code 998, 126, and 122. I think I may have some loose pins in my pcm connector :/ So I moved the loom a little bit then the truck ran normal. I pulled the spout while it was running ok, then it stumbled and died lol. So I'm tearing up my old harness I swapped with the same code to figure this out! Soon as it dries up outside I'll be testing like a mad scientist

Ok I lied. It's back now. Checked KOER test and still have 213. At least first time I checked it was clear but as a redundancy, I checked again and still have 213. Gonna tighten the pins now

Still have 213
So I had a spare distributor, got it installed, timed to 10, and still have 213. 225 also comes up randomly when I test KOER. 2 PCMs, PCM relay, 3 ICMs, 2 distributors, and 2 different wiring harnesses later, same issue. I even pulled the caps out of my old pcm and tested them and they were good. I literally have tried replacing everything. Not giving up yet. Anyone have any other tests? My knock sensor causing this issue maybe?

You have probably read where the knock test is only valid if you have pinging. Have your symptoms remained the same or are you only getting codes. I don't think you have addressed the smog pump yet. Sandy
