2002 yukon denali 6.0 Low idle So low the ac goes warm at lights or drive thru. Engine has never stalled out tho. Sits around 500 Cleaned the throttle body today. New plugs and wires today as well. Went to clean the IAC but I have this body.... First off Idk if this is even the one that is supposed to be on there or not but its what came with it. I say that cause I have found some questionable stuff the previous owners have done IE: replacing the front diff with a 4x4 diff that was disengaged so I eventually burned up my transfer case. So as you can tell it only has a throttle servo and the TPS. No IAC. Where is it? So I ask what can I do or check for the low idle issue and where is my IAC located? I thank you for your help!
