Thanks,

The dealer replaced the MAF in 2002 when I bought the car with about 120,000 miles. It now has 193K. I guess it speaks to the quality, anything I touch or work on looks brand new. Te MAF sensor looked great when I cleaned it but I guess that doesn't mean anything.

It's not showing codes for the MAF or oxygen sensor, but I may not be reading it right, But I will look into how to test OXY sensor over the weekend.

Thanks again
