Almost got to see the Halo... not quite though, still was a very small sliver of light creeping around the edge. Worth trying though. 3.09 pm here. I am in Florence, KY.
Identity of ECM: I can't say if it's really a B50 or a B51, I suppose if it makes a difference I could pull the board and get the numbers off it, could you identify it by that method?
Your schematic is a better match for the wiring in my '91 Samurai, not that this makes it correct. But you show a red/green wire on A16 for the EGR temp sensor which matches the '91-'95 1.3L diagram I have. (The schematic I was using showed it at A17.) I do not think I have that wire. Is the A connector the yellow one? I have to identify the pin 16 location but there are a few open holes. Do you have a wire with the attached pin connector? I'll need to make sure it goes in the right spot.
Resistor fix: I would have no problem with hooking that in at the ECM, even internally if it eliminates the EGR error, and then I could just remove the EGR stuff. If I understand your resistor fix then you basically just jumper the air temp sensor input to the EGR input? Again, identifying the connection points is critical but I have no problem with circuit board repair.
I think my sensors are in good shape, I've replaced both of the temp sensors. Idle rich condition is not extreme, sometimes rich on initial startup (have to flood clear to start usually when warm) and an intermittent rich miss at idle. Injector is stock and wires to it have not been abused.
I can go down your list of things to check but I'd like to clear the code 51 first. Is it possible that could clear up the idle? Could be an instant win.
