The truck runs but surges while idling but at this point I don't care I'm so happy to hear it run...... Thank you guys all of you I could not have done it with out the info gained from this thread...... Cj thanks for starting it...

Idle Surging can be due to couple of things:
Low fuel pressure
Vacuum leak
Bad MAP sensor
Lastly - you need to reset IAC - it must be set to minimum air position. There is a procedure posted (use search)
