2005 WK 4.7 Stalling issue.

Odd situation, My 2005 4.7 seems to stall in the following manner.

1) Must be a cold start , in the AM.

2) Only happens when I come to a stop.

3) Happens within first two minutes of start up.

4) Happens 1/50 th of the time, now around 1/20 of the time.

I only notice it when I hit the gas and nothing happens.

I run a gasoline antifreeze and occasionally a Bosch Injection system cleaner.

Jeep has 78 K, new plugs, air-filter at 73K.

I tried jiggling key while driving to trigger a tired ignition switch but no.

No codes via key dance and runs perfectly, smooth idle etc.

Any Ideas ?

Did Throttle body clean

Did Throttle body clean using Walts suggested way in the Sticky Section Took 1/2 hour , hardest part was wiggling out the clunky air box on top of the engine. Very easy and satisfying straight forward job. I held the butterfly open with one hand used two fingers and rubbing alcohol; along with a clean cotton t-shirt. That was it. Fair amount of sticky gook cam out with two or three wipes on all surfaces, including back of butterfly (clean surface every time going in, I rolled the shirt) . I have smaller fingers so I was able to go deep and wiggle around the plenum. it was kinda hot

Better 1-2 shift, Noticeable improved acceleration -

Hopefully cures the stall problem.
