However, I don't have a fast idle valve....

A vacuum leak or an improperly set TB screw will result in the IACV not being able to remove sufficient air and a code being thrown. Since you have an aftermarket TB my bet would be that a) your TB screw is improerly set or b) your TB plate is not fully closed at idle
