[QUOTE="golfer, post: 430747, member: 266"] how many miles are on the engine/injectors? rough running (or low power) when cold, but runs fine when warm...is indicative of high(er) mileage injector wear at the poppet valve. this valve seals the HPOil at the injector...and @ 200k miles is about the average for these valves to wear enough to not seal properly...nor allow the proper flow of oil into the injector..WHEN the oil is cold/thick. here's a link with more info: [url]http://www.swampsdiesel.com/files/7.3LInjectorDiagnostic.pdf[/url] [/QUOTE]
