#11 of 13 Carbon/soot in my exhayst pipe by g6soot Apr 27, 2008 (4:58 pm)
I have 3.5 and my milage is at 22 mpg. I can put my finger in the exhause pipe and it is covered with black soot. I have been to the dealer and have been told that everything checks out OK. In all my years black soot in the exhause is a sign of a rich mixture of fuel. Has anyone out there have an idea what steps i need to take to correct this problem..

Replying to: g6soot (Apr 27, 2008 4:58 pm) Almost any decent auto shop has an exhaust gas analyzer nowadays. If you think the dealer is incorrect, find an independent shop with a decent reputation and have then do a quick analysys. That should answer your question...
