While waiting for my new IAC (factory part off of Amazon for $128) I started replacing the plugs and plug wires. I went with OEM on both. Get this though, the sparks plugs were hand-tight! That can't be good. I replace two before I had to run some errands with my wife. Plugs were dirty and looked brown and white-ish. They were Bosch Double platinums.

I bet that's it then. I was definitely smelling spark issue. You may also have an IAC issue but getting the plugs right will make a huge difference, if not cure it completely. Keep my diagram for when you are done with the wires.

This is an old thread but I’ve seen lots of this exact same issue after the throttle body comes off and it has been because the air assist hose was not reconnected.
It must be an easy thing to miss. It can be other things, of course, but low idle and random misfire codes and hard starting point to the air assist hose.
