Idle air control location
 

I want to check my Idle Air control, but would like some help on location and what to look for when cleaning it. My truck won't idle and won't start unless I push gas pedal down, but will turn off if I take foot off gas pedal. I put new O2 sensors in the front. I also runs like crap engine shakes like it's trying to breath and exhast smells really lean.

Thanks
