Is the condition the same when it's either cold or hot?
Your FAST idle, will stay till the truck is around 175*F, when started cold. The initial HIGH idle our trucks have, is usually for 5~10 sec.
May need to be more specific as when it occurs.

It happens hot or cold. When shifting between gears it revs up a little then takes 5 seconds before it idles down. 5 speed trans btw. Anytime u push in on clutch like slowing down, it revs small amount then after 5 seconds it idles down

Sounds like a vacuum leak. Any original "brittle" nylon lines still attached in the engine bay?
When you say removed smog stuff, did you remember to cap/plug off vacuum lines needed for the TAD/TAB solenoids and EGR valve?
