# 13 is a EZ remove and clean!
I'd pick door #13 as my 1st choice to tackle 1st!
Although this is not your vehicle (it's my wifes 6 cyl Escape), it is the same the same problem that removing and cleaning may fix you up!

If this was not it, you just eliminated the IAC, as being the problem....12 to go!
Keep us informed

Aussie AU falcons have a problem with faulty inlet manifold gaskets, check that it is not leaking, often around cyl 5&6
