stumped
Ok so did you ever fix this problem? I am having the same issue with my LT1. I have a 1980 Datsun 280ZX with an LT1/T56 swap. I just installed a new opti with new connector and ignition control module. It runs great under any type of throttle. The only code I am getting is a lean right bank. The LT fuel trim is +25 but the o2 is switching normal. I know I have to do some part throttle and idle tuning yet. Could this be the cause of my problem? I have never seen an O2 sensor cause a stall but I guess anything is possible. What would cause the O2 to cause a stall? Is the PCM shutting down something for some reason...aka too lean?
Thanks!

Well mine seems to be the ECM itself. I checked codes again tonight and when it died on me it threw a 41,42, and 51. I checked my wires (for DTC 41 and 42) to the ICM as per Alldata's diagnostic flow chart and it lead me to faulty PCM(which is what code 51 is basically).
Hopefully I can get a new ECM tomorrow from the local salvage yard and load up my tune and be on my way!
