Default 1999 Flex fuel repeatable problem....

Hello,
When I first crank my 1999 3.0 flex fuel Ranger (160,000 miles) it runs great and will continue to do so until it warms up and I shut down the engine. After the re-fire it runs rough/skips until it cools back down.
I get no codes.
It will do this same sequence EVERY time. As long as I leave it running there is no issue...runs great.

Plugs, wires, injectors and coil pack have been changed.

Ideas??

Thanks!!
Keith

Just a shot in the dark; but try removing the IAC valve and give it a good cleaning. Might help to smooth out the engine after you restart the truck.
