Hi.

I doubt my 98 contour GL has a bad MAF sensor. Is there a way I can clean the sensor myself or have it checked?

The whole story is this car has been giving poor MPG around 17mi/gal. And lately the CEL was on (P1131). I replaced the O2 sensor but mpg is still low. I read some place online saying there's a good chance the MAF sensor is bad on this car.

Thanks!
