All right, I'm trying to think of reasons a car can run rich. My SHO is getting around 11mpg in Harrisonburg. I have already:
-Replaced the O2 sensors (~7k miles ago, old ones were throwing a lean code)
-Cleaned the MAF with brake cleaner
-Replaced spark plugs
-Re-grounded engine
-Replaced thermostat
-Run a tank of STP complete fuel system cleaner
To do-
-Plug wires (although the ones I have are supposedly 30k miles old and are OEM quality)
-Fuel filter
Here are the previous spark plugs - the car still seems to be running rich at this point (black soot all over the exhaust & pretty dark black smoke under hard acceleration, poor gas mileage.) Any ideas?? Cause I'm out of them and tired of thinking.

Why do people just post what they are thinking? Without thinking.
