UPDATE: BAD BATTERY I wouldn't have believed it if I wouldn't have tried it! I decided to start the vehicle then remove the battery cables. (Was curious if the alt and batt tests were wrong.) The vehicle ran fine without the battery. I then turned the headlights and heater blower on, still ran fine. With the battery disconnected I then hit the throttle. It ran great didn't even sputter! Connected the battery and tried the throttle and it stalled out again. Turns out the battery test given by (a well known auto parts chain) was faulty. Again, Thank you and the others for the advice!! It led me to the problem.

ok guys thanks, ive checked everything out and after reading a few suggestions i looked into the pcm suggestion and after reading on another forum about it getting hot and needing to be cooled down I tested it. I cooled the pcm when it started again the other day and it worked fine until it warmed up again.... going to get a new pcm tomorrow.,

wait, you are saying you were able to idle fine with the battery completely disconnected from the loop???? that is great, but i wouldnt recommend doing that for the simple fact that the computer likes a voltage signal from the battery, and im sure the alternator doesnt like that circuit being opened up
That is correct. It never stalled or had that massive hesitation. But when I reconnected the battery the problem came right back. Now the battery started the vehicle just fine. The morning I did this, I noticed the voltage gauge rising slowly after the vehicle was running. I understand the possible risk by running it without the battery but I just hoped for the best. But aside from the check engine light being on (from playing with the TPS connector), everything seems to be ok. Have to locate the book so I can reset the light.

Here is a link: Engine Code Index (Check Engine Light?)
Thank you for that link!! Saved me a whole lot of time. Still cannot find the book.
