Re: losing power

I have a 2001 2500HD 4x4 w/95k. I had a problem when towing a 8k trailer up a 6% grade. Truck did not seem to respond to acceleration after about 1/3 throttle. I changed plugs (ac-delco) and inline fuel filter both helped a bit but truck still doesn't seem to have the power it should. Did you have an opportunity or plan to replace knock sensors as suggested by poster? If so how did it work out?
