Default LT1 Auto keeps stalling at low speeds

My '95 383 LT1 has stalled on me 4 times today while I was driving at like 5mph. Battery/alternator voltage seems fine, temp is around 173 and it was running very rich this morning, triggered the SES light.

I don't have my laptop and cable here at work to pull the codes, which pins do I cross to get it to flash the codes? I can't remember which 2 to jump, I do still have my jumper wire in the car and a lot of people post on here that you can't get the codes but I've done it in the past.

Could it be a bad injector? The car has 126,xxx but the opti, engine, tranny, o2 sensors, tps etc. have 3k miles on them. Also, I just put new plugs (NGK TR5) in it saturday because I had tried 1 step colder (NGK TR6) but it fouled those as I think they were too cold. As of saturday there were 2 codes, both fan malfunctions (those are always there).

Throwing code 43: ESC Fail - is that the Opti? If so, ugh!

Update - replaced the LT4 knock module with the LT1 knock module and the code went away but the car still stalls
