Had an idle issue. With the new engine and stuff, the rear 02s disabled the rpms have a hesitation to return to idle. Stops off at sixteen hundred then fourteen and so on 'til idle but could take thirty seconds or so to finish. Fuel system cleaner and rear 02s enabled and some "spirited" driving and the idle issue went away very quickly. Thought I would share. Seems odd the 02 sensors to the rear made that difference.
