Anyone?

Having some issues with my 2007 Silverado ltz. Most of the time it drives fine but occasionally it surges and hesitates almost like a plugged fuel filter or bad fuel pump especially on really warm days. It is tripping the camshaft crankshaft position sensor correlation code P0016 but also triggered some misfire codes when it was really bad one day. I checked fuel pressure and it was within range and seemed fine although when I checked it the temperature was cooler out and the vehicle was cold. Any ideas on what could be causing this? Thanks
