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.
