been wrenching on my 01 F250. Truck had been intermittently stumbling and using excessive oil consumption (a gallon in less than 100 miles). So, I proceeded to fix it. From digging through power stroke nation.org and powerstrokehelp.com, I discovered I needed a cam positioning sensor and injectors. Bought said parts n a new magnaflow stainless exhaust (no muffler) and an AFE cold air intake. I also put in a new fuel pump, in-line filter and big (51 gallon) Titan fuel tank. Results are excellent. Oil consumption is null (I need to get some seat time in it to get real #s), and power is good. Cab noise is minimal. ZAlso, my timing is good as it snowed a bit yesterday when I went to get fuel.
