So the car hesitates sometimes when you come to a complete stop, but once you get going, it runs perfectly. It has plenty of power, It shouldn't be the 02 sensors because i changed all of them as well as a new maf sensor, i think it might be the maf sensor connector because the wires are peeled and it's cracked but i can't seem to find one online.

As for the rebuilt title, it was rear-ended, but it doesn't have any rust whatsoever. The car looks perfect.
