Rough Start and Power Loss
I have a couple issues. But I will be as brief as I can.
1. Ever since about 6 months after I got my 2007 F250 6.0 cold startups have been rough. I have used RevX like everyone on here suggests and it helped out a lot the first winter I had it. This past winter it really made no difference if I used it or not. But it wasn't overly terrible. But as summer came around and I expected the rough starting to go away for the most part, still using the RevX, it did not. I am guessing it is time to assess which injectors are giving me fits and replace them... probably going to be a winter project at this point and I am considering a EGR delete since I have began to notice a little bit of mysterious water loss and a general check of everything else while in the process. Does anyone have any suggestions to keep me from having to tear that far into it? Or does my assumption sound about right?
2. About 6 months ago after a 5 hour long drive, with one stop for lunch and fuel, as I rolled down a offramp I noticed the truck sounded a little different. When I went to accelerate it acted like it wanted to but it didn't. It would start to rev up a bit then just flatten out and bog down. I pulled over and shut it off. I waited a few moments and then fired it back up. And all was well again. I didn't think much of it at the time. Now about a month and a half ago I was driving about 50mph and it lost power again... basically the same issue by the way it sounded. This time I was on my way up a decent sized hill so I accelerated hard to see if I could at least get to the top. It bogged for about 15 seconds then came out of it... the turbo spooled up and she took of like nothing was wrong.... thill i let off the throttle then it was back to bogging down. I revved it again and it came out the same again. This time it stayed out and was ok. I got to thinking that maybe this has something to do with whatever injectors are causing my starting problems. But being that I am not a diesel guru I was only guessing. Well yesterday it did it again. And once again by revving it up a little it came out. I did notice that it was blowing black smoke like no tomorrow until the turbo spooled up and it began to accelerate. Any clues on this one?
My truck is stock. No mods of any kind. I would like to get her running nice and smooth again so I don't worry so much when I tow my camper. Any help is appreciated.
