Question about 2008 Mitsubishi Lancer GTS CVT Sedan
There are 2 things to affect the gas millage: 1- Air filter is dirty. 2- O2 sensor is bad. I give a feedback to ECM to adjust fuel injection to maintain the Air: fuel ratio of 14.6 :1. It is now running rich because ECm didn't know the ration is now < 14.6:1 since O2 sensor didn't report this situation so ECm didn't adjust fuel injection to meet the golden ratio. Check these out and replace them to address the problem. Good luck.
