i have a gsr block wiht ctr pistons and a gsr head wiht skunk2 springs. skunk2 manifold and retainers and stock cams.... i have the idle screw closed an its at 1000 rpm when idling.. it drops down to about 850 when driving then spikes back up.... any help would be greatly appreciated

 

Are you throwing any engine codes, maybe a 14?

 

I would guess you have a small vacuum leak somewhere... Honda's idle will increase, anytime the MAP sensor notices any extra air, from a leak...
