Mazda Mazda3 2008 2000000 miles
Already changed knock sensor after diagnosed, after driving for 3 days engine light is on again, so the programmer told me to go to an electrician, but no electrician has been able to solve the probs, only one told be its a prob with the box of fuse but not a major prob. And sometimes when i put my car on, the lights gets on by itself and gets off after 5 to 10 secs. The car has 200,000km as mileage
