My ScanGuage finally gave me a code today, it is the 0440 one for EGR problems. I have already tried removing the EGR and cleaning the pipes and EGR itself, so looks like I will install a new EGR and TPS as soon as I can. Still cheaper then buying a new car or paying someone to diagnosis and fix for me :-)

Doesn't feel like the Transmission is doing anything, and it doesn't feel like the torque converter is slipping or anything, just acts as if the throttle is opening and closing on its own a little with no change in pedal position. Just bouncing 500 RPM or so once it gets past 2k rpm (and is trying to maintain speed or speed up slightly). I tried fluctuating the gas pedal to match the type of RPM change and it does feel exactly the same as what it is doing by itself.
