1999 Chevrolet Tahoe code P1345

Replaced the catalytic converters, then replaced the camshaft position sensor then got a p1345 code, ckp cmp correlation. I was told I need to synch the ckp and cmp. Is there some kind of adjustment I need to do because of the new sensor? It runs good, just a intermittent miss or something when not accelerating. If you hit the gas there's no miss and it has good power. It's like a little hiccup when cruising at speed{60 to 70mph}.
