Well I got my problem fixed. I replaced the IAC and cleaned out the passage for it, replaced the fuel filter again, and changed the relay for the fuel pump. All that cost me about $60 and I still had the problem. My dad came over yesterday morning and we messed around with it and decided upon further diagnosis that the fuel pressure regulator was to blame for all of this. Picked up a fuel pressure regulator, intake plenum gaskets, and o-rings for the injectors ($115 worth of parts) and spent a few hours taking it apart and putting it back together. All is well now with the new regulator on there.
Just thought that I would share that so someone else might be able to use it. Seems like there are way too many unfinished threads around here with no end result to how the problem got fixed. Thanks for all of the other prior suggestions and help.
