Does it rev freely when not under load? Have you disconnected the exhaust at the cat and tried driving it?
GUys need help, completely LOST at this point...

No in a rev at stationary Parked/Netural IDLE, the stutter hesitation is there to a point like the engine will stall. Especially if you want to do a quick REV.
If you get revving it as the RPM's get higher, the Hesitation gets lower, and not worse. My friend FLOORED IT up a hill and it went up it with no problem. IS what he just told me.
If you climb the RPMs on the engine SLOWLY there is NO hesitation.

So guys i have officially given up and just have no idea what it could be
Just saying....
I had a friend with a similar problem. Hesitation, low power off idle. If the rpm got up there were no hesitation problems, drives great until you get back on the throttle. And the car didn't throw a code.
After going nuts for about a week and going through everything like 10 times. I found what the problem was. It was a blocked port on the throttle body. Cleaned the piece of blockage out and it ran like a champ ever since. I also went through all the vacuum lines.
This may not be your problem but I thought I just throw this in.

Since you are throwing parts at it is suggest getting a low mileage (<125k) throttle body off eBay. Lots of wrecking yards sell them for than $150. And you would get a newer IAC.

I finally fixed it:
It was a three parter: AN ignition coil had completely corroded on the connecting terminal to the wire, and a spark plug electrode was just completely gone, how the hell that happened I have NO IDEA. AND Spark plug on Cylinder SIX was LOOSE, NOT even screwed in.
I am not the original person who did the plugs, wires or coils. So whoever the hell did them screwed up bad.
What is weird though is it took TWO WEEKS for a misfire code to FINALLY come on and it said Cylinder 2.
But another weird thing was that wasn't the corroded cylinder either.
It's like the corrosion/short was screwing with the computer and completely pointing me in the wrong direction.
3 NEW ignition coils, and 6 spark plugs. Car runs like a dream now. I should of just checked the damn coils and plugs FIRST instead of believing my friend.
But she has POWER now baby, after new injectors, o-rings, seafoaming and new intake manifold gaskets.
FINALLY.
Edit: oh yeah and the wire attached to Ignition coil 3, wasn't even snapped on. How the hell this car EVEN RAN was beyond me.
Edit 2: I think I hold the record time for taking off the intake manifolds and putting them back on now.
Thanks for all the help.
