car dies at stop signs or low RPM's when in drive need some help on tuning my idle... everything is good except that when i come to stop signs i have to keep my foot on the gas a little bit to keep it from dying. when it dies the rpms bounce and then die. my IDAF and DAF are consistent with each other... my IAC is about 40 What do i need to do to help this situation?

If the iac motor cant supply the correct volume of air needed to support the motor then you will have that problem.
Sometimes you have to make the inlet for the iac larger to allow faster adjustments from the pcm.
You have adjusted your fueling tables for that cam right?

Sounds like your Running air Flow table is out of whack, Are you tunning it, with what? Jesse is also correct, could be your IAC count log it an see what numbers you are getting.
