My alternator went bad, so when I replaced it I also replaced the serpentine belt and spark plugs. After replacing these things the car will start but won't go above 1200 RPMS. So I bought an OBD2 Diagnostic Tool and was able to pull 2 codes, P2104 and P2112. From what I found on the internet theses codes mean, Throttle Actuator Control System - Forced Idle and Throttle Actuator Control System - Stuck Closed. I'm not sure what to do now. Any suggestions would be greatly appreciated.

Thank You

It's the 2.3L. I checked over all connections and they all seem good. I did try jumpstarting it after replacing the alternator but it wouldn't start. I had to charge the battery over night.
