Hello Mr Scotty I have a 2012 Kia Optima lx 2.4 Non turbo
I’m having a serious problem, Im losing a lot of gas mileage’s for the past 4 days I don’t know what’s wrong, I don’t see my check engine light come on and when I carry it to the mechanic to run it on the computer nothing came up either . I have 62 Milages on the car .I went ahead and get a oil change,change my spark plug also they flush my injector and my filters was ok.... But still nothing didn’t change I’m still losing gas like crazy I went ahead put it on a lift and there wasn’t leaking.........

No. 1-1


have a pro test the maf sensor data to see if it's bad
