F150

2001 Ford F-150

Engine Performance problem
2001 Ford F150 V8 Two Wheel Drive Automatic 133000 miles

i have a 2001 ford 150 every once in a while when I start my truck, I turn it on it revs really high then drops below 500rmps and dies. When I try and start it a few more more times same thing. When I let it sit a few minutes and feather the gas I can get it to run and then it is fine. I ran a obdII scaner on my truck and said my IAC was at 42.2% was wondering if that is where my problem is?

thanks
