Yes I re-used the intake manifold gasket as it was 2 weeks old and pefect shape. Yes im using uberdata. And it bounces around when cold and when the engineis fully warmed. It never did this before I installed the skunk2 manifold so it has somthing to do with that. All my vacuum lines are pefect and triple checked. I have no CEL's. I also thourughly cleaned the IACV and I just bled the coolant by letting it warm up without the rad. cap. I don't know what to do about the bouncing, but Im gonna try and adjust the set screw to stop idle ont he t.b.
