2002 Ford Escort Two Wheel Drive Automatic 101574 miles

Hi my check engine light turned on the other day so i went and got an oil change along and fluid check and fill done. My car is still having trouble with its throttle though. It feels almost like my transmission is going out. It drives fine when i keep a constant speed but when i am at a stop and accelerate it is starts of real slow and then gets real jerky. Anyways i had the guys at the shop do a quick computer check on my car and the codes P1120 and P0122 showed up in a pattern, one after another and each showed up 4 times. Please help me :D
