Hi! I've been messing with cars for 20+ years but I'm into my first TBI conversion without an aftermarket harness on an 84 El Camino. I'll post in the proper forum later but my issue so far is stalling at a stop, feels like the TCC is staying locked. The odd thing is this problem appeard about a month after the swap was first run. Never had a VSS (was waiting for the JTR unit). Now I'm not sure if it's because of a lack of VSS or something else.

Engine is a 90 305 from a G20 van. Used everything including harness and ECU. Trans is stock but freshly rebuilt 84 TH350 with a lockup converter. Eveything is wired and working except the ALDL/MIL, factory tach, VSS, and oil pressure gauge. Any help appreciated. Pics soon!
