my truck is noticably loosing horse power used to run 115mph now barely runs 85 its a 95 with 240,000 miles 5 speed with 3.55 gears

truck idles rough and runs rough and has very little ump like nothing after half throttle!!!!!

any reasons would be great checked filter fuel pressure and such

i need to check for fuel leaks but am just trying to find what expensive injection part to replace

yes runs terrible as temps warm up seems okay on a cool morning during the cooler months just started driven after it got hot because truck has ac but wont go over 85 and throttle is dead after half pedal

Plumb in a HPOP guage and do some troubleshooting that way. That many miles, injectors could get be getting tired also. Fuel filter is good? Air filter is good? Fuel press was ok?
