Default High idle

Im not sure where to post this at so I'll go here.

I swapped my ls1 intake for a ls6 intake last weekend. Ran fine and all is good but this weekend I take it out and it throws a code for running too lean. I retorqued the manifold bolts to 89 in lbs. I will have to see if that fixed the running lean or not due to
Possible leak through the manifold not sure. Anyways it's running in park at about 800-900 rpm when normally its about 700-750 in park. Drive it drops down to 600 or so which is normal but when I let off the break the car will accelerate and shift gears with out me hitting the gas. Not fast but over about 7-10 blocks the car got to third gear and about 25 mph without me touching the pedal. When I'm driving down the road at 60 and I pop it in neutral it revs to around 1800-2000 rpm.
What is going on? Mods are in sig with no tune yet. I will be getting a frost tune soon.
