Bank 1 Sensor 1???
Ok here it is. I know what the problem is but which side is bank one and which side is bank two? Which o2 sensor is one and which one is two? If I'm right bank two would be driver side and sensor one would be the front or before the cat. Would someone let me know if I'm right.

Bank 2 = Drivers side
Sensor 1 = before the cats
Sensor 2 = After the cats

I'm getting codes but thats not the issue. I just wasn't sure which side was bank 1 or bank 2. I would have to go pull the codes again but I think they were po131 and p1131 which is the o2 sensor. I have 104,000 on her so its about time to replace them anyway.

I don't plan to. If I'm looking at this right the front ones control the air/fuel ratio. All the rear ones do is tell you how the cats are doing. Of course the rear ones look like they are the easy ones to do.

Fronts are not that bad either. Trick is, remove the wheels and access them from inside the fenderwell.

I'll have to try that on the right side. The left (drivers) side is done. Thanks for the help.
