Default Wiring nightmare PCM Dead, Jim

My 95 S wiring has a crimp in the wire bundle between the engine and PCM, main power to E16, the crimp had been correctly made but not SOLDERED and corrosion broke it. I lost 3 days finding it.

Fixing it solved years of misfire! Blazer may be the same

Oh man! I have a love/hate relationship with faults like that. On one hand I'm relieved it is an easy and cheap fix, but on the other, I'm frustrated it took so long. Congrats!

This is also an important lesson regarding corrosion on wire connections!
