Finally think I found the problem with the help of you guys. My wife was driving home after dropping me off at work, and suddenly the car started missing and almost dying and the Check Engine Light flashing with the traction control light turning on and off with the engine light. So I got home tonight and pulled the code. I got a p303, cyl 3 misfire. So I pulled apart the ignition coil pack and swapped the two coils with the other and started looking at the new plug boots that I had bought and at the top of the spark plug to notice plug 3 had some odd tarnish on it. It was on the coil pack tip too. Upon further inspection found that the most inexpensive set of boots from Autozone mind you, was missing the metal spring that is used to connect the coil pack tip to the spark plug tip. So with that finally figured out back to the original problem at hand. So while I am trying to see if the light show was going to start again, the car started to chug getting back to idle. So I revved it more while it's in park and it seemed to continue to do so more and more. Perfect finally the car is having the problem while I can get under the hood. I started taking your idea about the IAC sensor and started feeling around near there and looking around it hoping I would hear or feel it making noise or something. As I was sitting there I could hear a hiss that sounded like a slight vacuum leak. So I looked and finally found a vacuum leak! YEAH! The vacuum hose from the intake manifold to the MAP sensor had rotted away and was collapsing on itself and had cracks all over it where it was beginning to leak. SOO, finally a long story short I will return in a couple of days to let you know if that was the problem and hopefully you can help pass the knowledge on for those having similar problems. Thanks again for all you help.
It works perfectly now. Thanks for all you help with this problem.
