ive been having an idle problem right after i installed my tb and plenum and i put back on the stock on and it still idles the same thing. theres no intake leaks so thats not it. but my check engine light is on and i pulled the codes from autozone and here they are if someone could shed some light on what they mean and what needs to be replaced thanks. also i replaced my tps when i installed the new tb and plenum.

P0113 - Sensor 1 Circuit High input
P1506- Manf Cntrl Veh.Spd. Idle Speed Control Auxiliary inputs.
