OK, in the last couple of months it has been dry, hot and dusty here in MD. I also experienced a loss in mileage with sputtering upon acceleration and what appeared to be much soot around the tailpipe. I found the problem to be a clogged air filter. Once I dropped it in the pep was back as well as mileage. I had just recently had the dealer perform the PIPs and new steering Cals for my 15' 3.6l and it didn't solve any issues. (the air filter solved most of them, it's often overlooked since it has a long change interval). YMMV
