You can get a code 21 if you run the codes with engine temp under 150 degrees. So if the car was cold, retry it once warmed up.
If car was at temp, I'd replace it

Did it smoke before?
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!
When i had the A9P in, it did not smoke like now. I will check coolant res and oil dipstick.
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
Does this O2 harness look like the one i need according to the colors and the jumper location?
Here are the 2 harnesses i have...can anyone identify these plugs to their corresponding year mustang?
