code help

[philly rs]

whats up guys, i got a quick question for u all.... my sister has a 03 3.8 manual mustang. now for the last couple of days the damn thing has been shutting off while she is driving locking up the steering wheel and turning the car off. (im thinking the power steering is shut down not locking up) anyway, today it started jerking while she was driving it to work. now untill then the check engine light has never come on, but after the jerking it came on and now it stays on. i ran it for codes and came back with po113, and po102. do any of u guys know what those 2 codes are for? any help would be great. cause lets not front, i know nothing about working on those cars at all and im not trying to mess anything else up on it, our engines are nothing alike so im turning to the experts.... u guys. thanks

PO113 is telling you that the motor is getting reduced airflow and PO102 means that your Intake Air Temperature (IAT) sensor isn't reading. Have you installed a cold air intake system?
