Also, it now appears that when you tromp it as you are going down the road, say at 50mph or so, the tach jumps up from 2k to 4k, making me think the engine is running fine, but the car still stumbles on its nose, so I am wondering if the transmission is somehow affecting it??? Don't know, but sure seems suspicious??

This sounds just like the problem that my buddiy was having on his Ford Explorer. I searched the Exploerer forum and found that this is usually caused by a dirty or bad Idle Air Control (IAC). Apparently during a cold start up the throttle plate remains closed and the IAC opens to allow a smaller amount of air to enter for a richer fuel air mixture. The IAC was not opening, which choked the engine and required him to have to push half way down on the gas pedal to start the engine. This forced the throttled plate to open and allow a fuel/air mixture. He had to keep his foot on the pedal until the engine warmed up and then it ran fine. After cleaning the IAC the problem went away. I used a throttled body cleaner to get all the crud out of it.
If you go to that online service manual that was posted above by tempfixit you can find a picture of the IAC and an R&R procedure. First find your vehilce type , year and engine. Go under Driveability and Emmissions Control, then under Electronic Engine control, and then Idle Air Control.
This is just an idea, it does not cost much, hope it is helpful.
