93 explorer PCM issues

[Bboy]

Question for you explorer experts. I put everything out of a 93 explorer sport (don't worry I have cool plans for the sport) into my bronco ii(engine, 5 speed, dash and harness) and before I pulled it I found out my explorer's PCM was bad, my buddy has a few 91 computers that I've tried in it but it causes it to surge between 2000-3000 rpms. Just trying to figure it out, I know that the 91 explorers only have 1 O2 sensor but mine has 2 so I'm wondering if 93 is the only year I can use since I also don't have a EGR. Also I tried soldering new capacitors into my original computer and checked continuity but it still doesn't run good (super sluggish, no power, throttle lag). Also wondering if there's a way to check that my "original" computer is the correct on for this harness/engine

I have 4 computers

Original computer code: F37F-12A650-YB. ANY1

91 Navajo computer code (runs best with this but still surge's):
F27F-12A650-TC X2X2

Other 2 91 explorer Computers: F07F-12A650-VA. EOL

You need a 93 PCM

93 has two 02 sensor
No cam synchro and no egr

94 pcm has a cam sensor and egr

So you need a 93 pcm for it to run correctly

Your factory 93 pcm was the ANY1 code? I may have one of these

Ok that's what I was kind of wondering. I was reading that one from a ranger might work? And yes mine was the ANY1 code so if you have one we might be able to work something out.

Yes 93 ranger is same pcm as long as it was a 93 no egr no cam synchro and same transmission

Explorer Explorer sport ranger and Navajo all same pcm

I will check for a any1 in my collection today
