[Quicksilver]

I knew the cap and rotor needed replacing as they have about 50K miles on them and I had cleaned the contacts instead of replacing. (out of pure laziness...)
So I finally replaced the cap and rotor and the crappy cold idle didn't improve so I'm finally starting some real troubleshooting.

Got out the pyrometer and cylinders 1, 4 and 6 are cold. 108° to 156° compared to 400°+. Can anyone see a reason why 2, 3, and 5 would be idling correctly but not 1, 4 and 6?
I know that the injector harness is split into 2 halves but unless my diagram is wrong it is split 1, 2, 3 and 4, 5, 6.

To add to the head scratching...
Once the engine is hot it seems to go away. Even when it is cold if I get into the throttle it runs fine, Blip it to clean it out and get on the throttle and it is happy. It has fresh NGKs in it, the Magnecors test out perfect, and it had new injectors less then 20k miles ago. Only theory I have is that maybe the injector timing doesn't favor those cylinders.

Anybody have ideas?
