Running Rich..

If I remember correctly, it threw code 41..unsure exactly.

However, which O2 sensor is the "common" one to go out? Or could my bronco running rich be a different issue..

:banghead stupid me disconnected the battery when installing the ECT sensor.. forgot to get codes after I lost the paper with the codes on them :duh

Is your fuel pressure regulator working properly, i.e. is it not leaking fuel, is there manifold vacuum to its vacuum port, is the fuel pressure 39-40 psig with the vacuum line removed and 32-35 psig with it attached?

No idea..but I can find out! I just replaced the valve covers and need to figure out where this one hose goes.. until then I don't want to start it.

I'll have more info tomorrow on my tests (no life, no plans, work on Bronco tomorrow)
