I have a GS430 2001 with 114k miles and just got my first CEL. I had this same problem around the same mileage on my Honda Prelude.

Anyways, anybody know of any good mechanics in Orange County, CA area that does this for a decent price?

I'd do it myself but i read that the Bank 2 o2 sensor is a ***** to get to.

thanks.

on a side note, AMMCO tried to charge me $40 for a CEL read.. and i told them to shove it cuz i could just buy one for $50 at Auto zone. I originally went to Autozone for the free CEL read, but apparently they stopped doing that 2 years ago cuz of legal issues.
