Suck my DX

so i was just drivin along today when my check engine light comes on...and as soon as i take my foot off the gas revs drop and motor dies..i start it up and it does the same thing..so i look and the ecu is throwin out cel 14 for the iacv...so i played around with the idle needle and its now running fine..but the cel turns back on like five seconds after i turn the car back on..i disconnected all the sensors and the battery...waited five minutes just for the hell of it and plugged them all back in...the car starts and runs but the light turns back on almost immediately after i start the car...so my question is..where is the iacv and what needs to be done to fix the problem? any information would be appreciated..thanks
