I took my car to a mechanic to check why the CEL was coming on and code 48 came up, LAF (linear air flow sensor)problem. Has anyone experienced this? I'm getting on average, 28mpg. I'm getting horrible gas mileage for this car. What should be fixed or changed out?
I'm hoping that if I change out the o2 sensor, it will improve my gas mileage as someone said it would earlier. Did any one here have the same problem, and if so, did changing out the o2 sensor fix it?
