The engine is a 355 sbc with Dart SRP heads. Everything else is stock. But your right, it seems rich to me as well. Hoping once I get the o2 sensor hooked up I can get some better logs on it.
What I meant to convey:
1. It should be going into limp mode, and if you do not have a TPI MEMCAL (preferable AUJP), it will not run. For example, if you have a MEMCAL for a 6 cyl or a carbed v8, all the parameters are incorrect for your engine so it can't run, or at least not properly. What do you have? Look at the info on the back of the MEMCAL. If you can't read it, remove it from the ECM and pull off the blue cover.
2. I don't understand why your log does not show Err 13 being set., but it's not worth running it again to find out until you get an o2 sensor, unless you want to. If done, then after it dies, short pins A/B of the ALDL connector with key on engine off. Should blink out 13 and maybe other codes.

PS --
Not mentioned in the first post -- Once you install the o2 sensor, you might consider following the procedure for setting the TPS voltage (and IAC). TPS voltage is presently 0.71v and above GM spec of 0.54v. Some will set it up to about 0.65v. But know that 0.78v is the critical value. Anything above that and the code assumes the engine is not idling. Not good. Also related to proper idling and determination of other issues is the absolute need for a VSS. Some try to run without one, but many things are affected if not installed (most related to how o2 sensor readings are interpreted because VSS pulses are used to determine if above or below 15 MPH for may o2 related decisions -- all of which affect BPW calculation).
