I'm gonna go with ecu/sensor problem. IF it was fuel pump it wouldnt run fine cold unless it wasnt the car acatually getting warm so much as the fuel pump ovrheating. IF it was the Dizzy than it wouldnt run right cold either. Try your aunts ECU if you can, also run it hammer it off the stuttering for a sec then pull your plugs immediatly, take pictures and report back. I want to see if the plugs are showing that the cars running lean. IT sounds like an open loop problem, perhaps when u are easy on the throttle closed loop gives it enough fuel but open loop then kicks in and makes it lean thus stuttering. This is weird, I have never heard of a corolla having weird domestic car type problems.

Figured it out. Was the dizzy, or IS the dizzy.
Plugged in my aunts and after the car warmed up it felt good bouncing the car off the rev limiter at wot.
Took a while to get around to it, taking 19 units plus the **** teacher for my statics class is making us do another project outside of class which eats up another 6 hours per week.
Still do not understand why the dizzy was affected by engine temp, because when i took out the tstat, the car stayed cold and worked fine (save burning more gas and me not being able to use my heater)
Tstat is back in so worries, picking up another dizzy at the boneyard tomorrow
MANY THANKS TO EVERYONE WHO HELPED OUT!!

I agree its an abomination. But its all i have at the moment. Going to be rebuilding the stolen hatch, this time i'm taking some precautions with anti-theft.
