After the success I had with replacing the front O2 (fuel-air-ratio?) sensor on my wife's '99 Camry (CEL came on at ~84k), I think I will try the same on my '96 (152k, no CEL) to improve fuel economy. Fuel economy is in the 20 mpg range (City), and I think this will do the trick.
Does the Denso 234-2058 come with the flange? The 234-2050 and Bosch
12211 I think do not come with the flange, and must be installed into the old flange with a tool - ??????I'll likely go with the Denso 234-2058 at rockauto, unless someone has a better suggestion...?
Thanks,
Michael
