O2 sensor(s), '95 1MZ

[toyomofo]

'95 v6 Camry 142K. I'm slowly getting my Camry up to par. The check engine light has been on for almost a year, so I finally got the computer scanned a few days ago. It came up as

code: P0135, O2 heater circuit bank, bank 1, sensor 1.

The guy who did it showed me that she's fluctuating (and working somewhat), and the car runs well. He reset it but the next day it came back on. He told me that I might want to change all the O2 sensors since the car is approaching 150K, and that the one that is causing the reading is probably next to cylinder 1. He also told me to check all the fuses with a test light first.

Since I'll be attempting this myself, I was wondering if you guys have any tips (especially with cutting and soldering the wires) and if there are better/worse brands of O2 sensors.

Thanks

I only go OEM. Thats just me, but I like quality.

For the rear sensor (by the firewall), get an 02 socket at the parts store. Like $10. I got mine at AutoZone.
