I was thinking Throttle Position Sensor the whole time reading your description, but you mentioned you replaced it... when you lower the gas, does the engine rev up higher and higher but your speed remains constant until it's Full Open Throttle? or do your RPMs remain low until you get FOT and then you also get acceleration? If your rpms climb but the car doesn't accelerate, I'd be willing to blame the transmission.. if you don't build any rpms until you're FOT, then it could be the throttle position sensor still (could have been installed incorrectly?) or probably something in the fuel system... either the injectors or filter are clogged up... when you push the pedal down enough, you're pushing enough gas to get past the clog... but not until then..
Dunno, kinda shootin darts in the dark... I'm a computer guy, not a mechanic... but knowing how the systems work (in generalized detail) has drawn me to these conclusions... if someone more mechanically enclined has other advice, I'd strongly suggest taking theirs over mine.

Hi - thanks for the response! I have an automatic (grr...I ordered a manual and after waiting 3 months and the automatic arrived at the dealership, I was told to take it or I wouldn't have another chance - since I live in crappy Arkansas...I believed them...hehe!).
The RPM's remain low until FOT and then the acceleration kicks back in - the code that keeps coming up is the Throttle Position Sensor, so they went back in and checked it again, and it's installed correctly. They tried a new diagnostic machine, and it appears that there may be something lodged in the throttle body itself.
Thanks so much for the insight! I've learned more this week than I ever wanted to (hehe) Hopefully, it will be repaired soon - because this girl is tired of being stranded!
