Figured I would reply in here with my chargin' issue also so that way others will know on it.
Before I got the truck running correctly I had a cluster that had the voltmeter bad and the surround was cracked. I had gotten a 94 cluster which has different circuts.
After putting a brand new alternator on it still wasn't chargin' the battery. Sure enough the circuits being different caused the thing not to charge. My fix was take the voltmeter and gas gauge from the 94 cluster put it in the original 92 cluster and take the cluster surround and glue the correct light indicator thing on. Sure enough put it back together and she now charges the battery.

173 code came back after driving the truck again and it started bucking a bit.
Dad thinks the throttle body is dirty and the emissions codes are messing with it.
Me I don't think the egr or thermactor has anything to do with it because I have both the same codes on my 88 302 and it has never once ran rich actually she runs great.
I am thinking maybe the computer truthfuly but dad is so stubborn about it not being it he won't pull it and I haven't had the time just yet.
It still was puffing black smoke but it was so cold and snowing that I couldn't see how much while driving behind dad in my 88.
I got a new radiator because the one in it seems to have a clay like substance in it and since we are getting a 116 (and 113 for ACT according to Oriellys code reader but not mine?) code again also I am wondering if the ECT needs cleaned. The coolant sender unit must not be good either because it only gets to just before the N and won't go up.

The coolant temp hovering around "N" is normal, and don't expect it to always be there, it might hover around the "R" next week if it feels like it.
Its only an issue if its overheating, the gauge just isn't accurate.

Are you getting different codes at different times?
Sounds like the PCM is having problems. Easy check is to pull the connector for the ECT, ACT, or TPS sensor and check the 5 volt reference line. If it fluctuates consistently then that points to bad capacitors.

Pulled the computer and there sure enough was a leaking capacitor. I guess I should have listened in the first place sorry guys.
As far as the coolant temp gauge Big bad Leroy I don't fully agree I have had quite a few of these trucks (granted no 6cyls) and everyone of them stay right behind the N and the O unless they start overheating I have never had one run properly while under the N.
Dad has a certification in electronics so he is going to try replacing it.
Also is it normal for a 92 to have the computer come out from under the hood? I usually see them come from inside the truck.

Yes, 1992 and newer trucks the PCM comes out on the engine side of the firewall.

Well put a new resistor on and it still is running terrible. Pulled codes and sure enough
got on KOER:
116 (ECT and yes it was at tempature because he drove the truck 22 miles to where I work before he pulled the codes it seemed like it was running ok then)
114 (ACT)
173 02 detects rich
332 (egr)
225 Knock sensor (still don't understand that)
I think I just need to buy a brand new computer because it did seem like it had bubbles on the board (dad says it is the coating but not 100% sure)
computer part number came as a federal emission 4.9L Stick shift which is as far as I know what this truck is.
I will do the test timbersteel says and see what it does and report back but won't be able to do that till tomorrow afternoon after I put a new relay connector on my 88 and fix that issue.
EDIT: also those codes were in that exact order. I though the codes were suppose to be in numerical order.

Looks likr KOER codes? If so...start with KOEO and CM display.
Either way, if you are getting ECT and ACT codes after running for 20 minutes you may have bad sensors or VREF is out of spec. Looking a lot like a bad computer.

It was a 45 minute drive to down 22 miles.
Yes those are KOER codes above.
Only KOEO codes I get is 522 (vehicle not in park or neutral which it was in neutral) and 116 (ECT but it only comes up sometimes)
Only CM codes are 111 and 116 varies each time I pull the codes Once before I did get a 332 CM but it went away right after trying it again.
What is a VREF not sure I remember that acronym.
Thanks for the help guys

If its actually correctly reading the temp I have learned something today!

If your isn't consistent I would look at some of your cooling system parts. They may not be bad where it is overheating but some might sticking or slightly clogged.
Sorry if I sounded rude when I posted that I didn't mean it that way.
