Hello guys.
I am having a serious headache due to the rate of fuel consumption of my murano 2003. There is something not just right and my Mechanics have not had any success fixing the issue. I have changed the 6 plugs, had the injectors and air flow meter checked and cleaned, the fuel pump has been changed. The best I could get from my car is 6mpg on an average. Can't be more frustrated. My thermostat is functioning.
What could be the issue? Not sure how one of the catalytic converters got stolen by a dubious mechanic. My new mechanic showed me where the cat was removed and sealed off. Could this be the main reason? A machine/computer diagnosis was done by a friend and it found the oxygen sensor faulty. However, My Mech told me the sensors are not actually faulty, just that the missing car converter will make the sensors appear faulty. Please I need a solution. On the verge of loathing this car forever. Please help.
