Looking for direction on where to start... Rough idle, rough start, near stall

I have a 96 crew cab with electric fuel conversion from the PO.

About a month ago the truck started taking a little longer to fire up in the morning. When it does fire up, the RPMs immediately drop real low then it comes around and idles normal. After sitting for a while, it will do the same thing when starting up. If warm, the truck fires right up fine.

The starting thing has progressively gotten worse. Now, when coming to a stop the truck starts to act like it is gonna shut down. The idles gets real low and it begins to lope. It hasn't died yet, but it makes a convincing argument that it is going to. When I hit the pedal, it takes off just fine. Come to the next stop sign and the RPMs drop into the 200-300 range.

I have also noticed the tranny seems to take a bit longer to shift. Going from 1-2 seems to be dragged out a bit and isn't as crisp.

I replaced the CPS about 6 mos ago with one from the dealership. But from what I have read, that could be a suspect. My research turned up a number of things...

1)Bad torque converter not releasing and bogging the truck down
2)Faulty CPS
3)Low oil in the engine and HPOP (checked both and levels are good)
4)Ebpv gone bad
5)ICP sensor faulty
6)IPR sensor faulty
7) others?

I am hoping to get some help. #2 and #3 have been addressed. But could the others listed cause the problems I have suggested?
