6.0- The Dark Side!
My '04 is still bone stock. Delete and exhaust is in the plans but it's only money, right?? New EGR valve last August. New injectors and fuel filters 2500 miles ago. Has been running awesome. A month ago maybe I started getting some black smoke and low power at low RPM and heavy throttle like you would going around a corner or starting out from a start. Felt like being in too high a gear with a manual and was lugging until the RPMs got higher. I even had smoke passing on the freeway the other day. Never did this before that I ever noticed (the smoke). I figure I better get it scanned and go from there. Have an appointment Wednesday. Before I take it in I figure I can check the EGR so a week and half ago I cleaned it. Wasn't horrible but it seemed to actuate better. Reinstalled with new gaskets. Watched a video on cleaning the intake port going to the MAP sensor. Checked it, wasn't blocked but made sure it was clean and the hose was clear. Problem remained. This last week had to make three highway trips. First one still have the problem. After that it seems to be getting better and yesterday I couldn't get it to smoke by romping on it. I think it's running like it did before now. Seems to have fixed itself?? I'm wondering if there was some carbon built up somewhere that finally blew out. I know I need to drive it harder and I try to wind it up when I can (love to roll down the windows and listen to the turbo!!) but I'm not always on the freeway. Just wondering if anyone has had this happen and should I still get it scanned? I was going to talk with my mechanic anyway but I'm a little stymied. Sorry for the long post. I think I included all the pertinent information.
