Ok so I have been trying to figure out what is going on with the wife's escape. It has been idling rough and stuttering on take off. A Google search came up with it being an idle air control valve. I turned the air off and it runs fine so I thought that was it...except that I looked on the parts site and at autozone and the consensus is that there is NO iac for a 2011 ford escape xlt 4cylander. Thoughts?? Every search keeps saying its the idle air control valve but no search shows one for 2011 escape...thanks in advanced for any help.
