I have noticed an accumulation of soot at the exhaust tips on the rescue srt when washing the car. I assumed since the car is running well and that there were no codes that all was fine. By the way...I searched the forum for "soot, exhaust" nothing came up, so I started this thread.
~ The amount of soot lately has seemed to increase and the CEL came on yesterday, so I'll hook up the scanner and get back to the thread on this issue...
