Well, I do have a “doomsday box” which includes everything needed to switch over to dual Solexes, but something always brings me back from the edge. I used to think of better gas mileage as an incentive, but the other day I was looking at owner's manuals and noted a sharp drop in gas mileage from the 1500 (30mpg) to the 1600 (26.4….just like FI). I do worry, though, about the lifespan of FI parts. That failed brain could have been 48 years old!

Jim….I’m happy to send you the failed brain. I’m curious to see what happened. Of all the old ones I sent you, I’m pretty sure only one wasn’t able to start the car. I wonder if it’d be possible to compare the two. 

As to whether or not the new brain fixes the warm idle lope, we’ll have to see after I drive for a few days. However, I think it’d be a pretty serious set of coincidences if the warm idle lope (which would eventually stall the engine), the   stalling every time I got off the gas in traffic yesterday, and the death of the ECU were not all related.
