Stalling 98 Jetta with check engine codes!

My 98 Jetta has been having trouble idling. Also when it is in second gear, it kind of gasps for breathe and feels like it will stall. I took it in and got the check engine light codes from autozone (for free!), and they are as follows:



P0103-MAF or VAF circuit high input

P1127-Manufacturing control fuel and air monitoring



Does anyone know what this is and how I can fix it? IF I can do it myself? It is an old car, but I am a broke student so I am hoping to keep it together till I can get out.

Thank you.
