doesn't sound like th O2 or IAT (don't these only/mostly matter after the truck warms up?). You may want to check the IAC. I have had dirty ones create similar problems, just be careful claening it if they are like most (are they sensitive to movement anyone?)

I just changed the IAT in my '96, 5.8L. The only reason I changed it was because the MIL light was on. I didn' notice any differance in the way it ran. I bought a scanner, and pulled a P0113. Ford calls it an air charge temp sensor. Ford wanted $37. for a new one. Seems like a fair price.
