Idle issue

My truck seems to be confused. It idles Low when cold, then high when warm. How should I go about fixing this?

I'm sure there is another thread that covers this already, but couldn't find it.

Check that the fast idle cam is working right on the carb.

The choke and fast idle mechanism are probably set up incorrectly, and the curb idle was most likely increased to keep the truck running while cold - the side effect being that it idles too high once warm.

Take a look at this thread for properly setting up the choke and fast idle: https://www.ford-trucks.com/forums/7...ml#post6422219

Once that's dialed in, you'll want to set up the rest of it (curb idle, mixture): https://www.ford-trucks.com/forums/1...l#post11216172
