Update:
The car so far hasn't stalled since I fiddled with the pressure adjustment for the EHA and the fuel mixture at the tower. As matter of fact it seems to have picked some extra power while idling very smoothly.
I also noticed that it no longer backfires, the oil pressure gauge does not fluctuate as wildly and I think this is important, the fuel economy indicator is no longer at or over 1/4 from the left when I am at a stop in gear; as matter of fact it's almost at zero.
I tested the car in Washington DC and Baltimore traffic during rush hour but it's all good.
Let's see if it holds up for the rest of the week
