Hey all, New diesel owner, 350,000 miles. Just started "missing" and sounds kind of loud and rumbly. Just adjusted valves and replaced both fuel filters and that didn't help. Fixed a couple vacuum leaks, still no good. What's Next?? Never really worked on a diesel before so I'm not sure what to do, or what these symptoms mean. Replaced the turbo a couple of months ago. The car ran great before, but now sounds like it is working way too hard, and it can't be doing it any good. Injectors maybe? Plugged exhaust? I'd like to get another 350,000 out of it. Please give me some hints!! Thanks, Tom
