I would still pull the code first before replacing anything.
I haven't worked on too many Zetecs, so I'm not positive on the porting of the IAC passages, but do they go through the manifold or the throttle body? The reason I'm asking is that it's possible that the passage may be blocked internally in the TB or intake, either by gunk, gasketmaker or gasket. Just a possibility.
It brings to mind a problem a friend had, back when I used to build up V8s in my youth; a friend had replaced the intake on his 302 with an Edlebrock, couldn't figure out why he was running so hot. He replaced the thermostat, rad, belts, still no go.
I asked him why he went about throwing parts at it; all things being equal, rule out what YOU did first.
It turned out that the manifold gaskets he got from Crappy Tire were defective -- they forgot to punch out a water jacket hole, the water pumped into the head and couldn't exit into the manifold fast enough.
Another mistake I see a lot of people make is gooping the bejesus out of anything and everything with gasketmaker. Unless it specifically calls for it, it's not needed so much. Sometimes it actually makes it worse. Just some free advice, no offence.
Can you try putting the old TB back on?
