2010 Ford Flex Limited 6Cyl3.5L - Engine
Engine is 3.7 6 cyl, twin turbo, exhaust is to rich, black soot visable at exhaust. How do I lean this out, >MPG ?
No smoke comes from the exhaust, just the black soot residue on the inside of the exhausts. There is no turbo lag, probably because it runs so rich! Is there any way to lean this out a little? Chip?
