Because the injection program needs DOS I am running all this on what must be a WWII relic with Windows 95 as the OS. I save all these to a floppy but that computer is the only one I have that still has a floppy.
Jeff,

The things to look at would be:

1) What does the AFR reading do at the time of the stumble?
2) Is the system providing any transient fuel (enrichment) related to the change in throttle setting that causes the stumble
3) Does the fuel or timming program make a bit move in the VE%, Timming, and/or target AFR before, during, and after the stumble
