well, replaced the tps sensor again and same problem exists. Upon driving it, i did figure something else out. It's not position on the gas pedal that does it. If i barely put the gas on, and ever-so-slowly add to the pedal, it's fine. And it doesn't show the symptoms when i floor it because its in the higher RPMs. If the engine is over 2300 RPMs, it doesnt have a problem... so if i drive with OD off it's OK, but i still have red lights, so that's an issue. just thought you guys should know it's only under about 2300 RPMs. Sounds like a vacuum leak to me, or maybe the IAC? If it's in neutral, at idle, the IAC tapers up slowly to wide open when it starts messing up. That leads me to believe it's a fuel problem... but pressure is steady... so i'm very confused.
