[Tom Joad]

Hi,

I've just checked my Tahoe and found out that those two codes are back : P0135 & P0132.
only about the Bank 1 Sensor 1 sensor.

I've checked http://www.obd-codes.com/p0135 and http://www.obd-codes.com/p0132

I'm thinking of replacing this O2 sensor. ANything else I coud/should do?

I had the p135 on my 2003 just 2 weeks ago myself and I only did the single sensor. I didn't see any reason to replace the others if they're still fine.
Getting the harness de-attached from the side of the tranny bracket was a PITA and there was an odd factory retainer keeping the plugs together. Had to use a small ziptie to emulate that. This is extra, over the normal click/snap plug attachment.

I ordered four of them for two reasons.
First, because of the shipping fee from Rockauto an taxes.
Follow me there. When I did the order I was ordering 2 trunk shoks for my MAzda MX6. $20 of parts and $35-40 of shipping fees.
Since the O2 sensor are shipped from the same warehouse I have 6 parts for the same shipping fee.

hte other reason is simple : usually when a part fails, it means that it's counterpart will fail soon. I'll have spare parts if this happens.

On the 05 the bank 1 sensor 1 02 sensor from ACDelco had the barbed plastic retaining pin attached, so I just snipped the old one. It is very tight to reach the sensor harness plug. I had to jack the frame up to make it easier to move under there and slide under the step rail.
