Default THE CODES ARE IN!!!!

i know they're now VAG codes but they should still work right...?
went to autozone.. rented one of those contraptions they have, plugged into car and got the following;

P0103 - MAF or high input circuit
P1504 - MANF cntrl. velt. spd.
idle speed control
auxilary inputs
P0121 - TPS/pedal position sensor
a CKT range/Perf.

already tried cleaning the MAF, d idn't work so i have a new one coming in today.
the second code.. i couldn't get the idle control valve all the way off so i tried sprayin some cleaner in with it halfway off which didn't seem to help .. have to w ork on getting that ALL THE WAY off today.
As for the last code.. pedal position sensor? wtflip is that??
feel free to let me know if i misinterpreted any of these codes.. THANKS!
