New to the forum, but not to diesels. I've had many including a couple of semi trucks with Mack and Cummins engines. I currently have a 2004 Excursion with 191M miles on it. Runs, looks and drives as if it has 40M. My only issue is that it seems to need just a little encouragement to start, but only once the engine is warmed up. If I hold the accelerator pedal down about 1/3 of the way, it seems to help. It does start, but it just doesn't bark to life like others I've owned. Starts cold just fine. I haven't had this very long. I bought it from a Ford diesel mechanic who owned it since new. You can tell by how it looks and runs that he took very good care of it. Even has the red Caterpillar ELC in it. He says he replaced all of the injectors less than a year ago, but I don't know what else he had done. Runs awesome, NO smoke of any kind, NO leaks and I get 18MPG on the highway. Anything particular I should keep an eye out for?
