My pops was a mechanicbefore he retired and "rich" was the term he used. he asked me why my car was running so rich and that I should have it looked at. When I asked what he ment, he reach down and wiped the exhaust pipe with his finger and showed me that there was a lot of black soot on his finger and followed that up by saying the car is not using all of the gas properly and that's what's causing the excess black in the tail pipes. Now before he said that I took noticed that I'm averaging 15.3 mpg at about 23ish mph since my fill up two days ago. I have a v6 but I just thought the terrible mileage was from me lead footing it from most stop lights and such. What do you guys think? The only mods in the car are a CAI and an mrt v2 axle back setup.
