Hi all I have an 97 K2500 f-vin 6.5ltd auto trans. The truck runs great except at hard acc. like 3/4 to full throt. then it almost feels like the trans shifts up and down real fast but it is the engine surgin. The lift pump is newer and the truck idles fine with the water drain open. I was thinking fuel filter but it only has a few thousand miles on it. I am running an anti gel as is has been in the teens here in buffalo all week. Any Ideas? thanks Adam
