That should solve all of the problems you just described. Mine exactly the same symptoms, and they all disappeared once the idle speed was reduced.

Yea, that's the idle screw I was talking about. At this point I've tried adjusting it to nearly it's full range and the thing still won't idle right, it also is still the engine code listed above.

Do you (or anyone with a 1zz throttle body) have the symptoms I described in my post above? Particularly the long throttle hang when you take your foot off of the gass, and the hiccup when you press down on the gas?

At this point I think I am going to buy another 1ZZ throttle body and chip swap it in my spare time.
