You did reset the computer, disconnect the battery and turn on the head lights for 10 or 15 minutes, turn off headlight connect battery and drive it then check codes.
Smoke could be a mechanical condition and nothing to do with the ECU or wiring. Usually running rich due to programming is a black/dark smoke, while a while smoke could be coolant or burning off some sort of oil.
Thats exactly what i did not do—run it at operating temps. I just let it idle for about 5 minutes...i guess its not at temps when idled, so i will try and go at it again.

I did not do that resetting process...i just removed and replaced the ECU after disconnecting the negative battey lead. I will try what you mentioned, thanks man!

so the pin locations on my o2 harness should be 1 and 6 for a 92 with a manual? if you look at my post on page 2 with a pic of my o2 harness, it looks to be in the correct position, 1 and 6. I will need to check when I get home for confirmation because im not sure if that's a pic of my old harness
