Ford TFI-IV Ignition Module Woes! New Defective Parts for a 37 Y.O. Clean Bronco

This video is about Ford TFI-IV Ignition Module Woes where we had two new TFI-IV ignition modules cause intermittent engine stall events. In this video I walk though the pain points and failure modes multiple replacement Ignition modules presented us with and what we had to do for an ultimate fix! We review the PIP and SPOUT signals using the Picoscope to identify faults and specific control circuits and how to identify faulty control circuits.
