Sorry it has been so long for a update. I got 12 trips to work for a total of 270 miles and used 18.8 gallons of gas. That is about 14.5 mpg. All the milage is from mapquest. My odomiter is way off. Any ways it is running better then ever and has far exceded my expectations of mpgs. The wideband o2 sensor gauge is pretty solid now. Only moves when i move the throttle. Would deff do it again.
