Well Son of a Bitch!

I'd have never thought of that and was not even going to try, but I'm glad I did. Soooooo much better. Maybe it's tunable now? I've got to solder and shrink wrap the two crank sensor wires and try again. I had them twisted and taped and if I pinched them it changed something...

It actually idled... almost. I've had the external IAC pinched off because the Jeep IAC is backwards? IAC counts of 0 = full air! Tried to put a GM IAC in the Jeep IAC housing, although they look identical a closer look showed enough difference that it won't slide into housing. Wonder if swapping 2 blue or 2 green wires would make it work right?
