OK a little update

I changed out the 4.3 injectors for 3.1 injectors and the stumble/struggle at idle was less frequent. IAC still has to save the day and keep it from stalling, but not as much as before. BUT (and I found out something by using a computer tuner) when the engine starts to warm up and gets around 130degF the computer wants to start to lower the idle rpm from 1000/900 to 600. When it starts to do this, the engine struggles and stalls. Im still guessing to much fuel.

I have a few more things Im going to try and then Im taking the leap to MS. I want to try the 3.1 computer as well as the 2.8 injectors. Im not positive that these will fix it but I have to try.

Ive been talking to EFI-DIY about the MS system and will be buying the unassembled kit and the 746/747 adapter board if the above don't work. Nice thing about the MS is if I ever switch to a different engine (inline of coarse) the ms is adaptable. Total for the MS system comes to about $400.
