Year: 2/2004

Mileage: 137,500

Indications: SES light, codes (2), car is running strong and pulling hard. I have noted....the last few days my idle is down maybe 100rpm (down to 6 from 7). I thought maybe I wad just seeing things though....maybe not.

Relevant Previous Maintenance (All complete in last 5k miles): Precats replaced, New fuel pump, new plugs, cyl #1 coil pack, ICV/DISA/Both boots inspected, TB cleaned.

Last fillup: Last night w/ Shell 93. Code came in approx 25 miles later. Just sayin....

My Guess: Failure of MAF sensor.

Any and all ideas are welcome.
