So here's my problem, The car is fine when it is cold, no problem with power when it is innitialy running but after about 10 killiometers of driving it gets flat spots when accelerating around the 2500 rpm but after about 3500 it seems to be fine, i thought it was a flat spot in my tps but i just had it replaced about 3 months ago so i couldn't be that. Also when i floor it around the dead spot it really gives a lunge and then takes off,

Anybody know what is causing this?

 

I know you said your TPS is new, but is it properly adjusted?
