Posted previously about '03 LE with 9K having a failed Air Fuel mix sensor.
Covered under warranty but has been a circus. Took about 10 days to get the first replacement sensor. toyota installed it and everything went haywire.
They kept car for extra day and they finally decided it was a bad sensor. Ordered another one....took a week to get it. They installed it and it all went screwy again. More time on the phone between toyota dealer and some "mystical toyota experts sitting on pillows in a far-off land."
They finally decided that my Camry, which was produced in June 03 used a different sensor than that that is specified in the parts catalog, even if they pull up that part via VIN number. So, anyone in a similar situation might want to be aware of this little glitch. Cheers, tim
