RE: 02 sensors, where are they?
The Pre-cat (Bank 1) is located on the downpipe. You can see it if you look on the backside of the engine between it and the firewall. The other sensor is under the car on the exhaust pipe just downstream from the catalytic converter.
How do you know you think you have an issue? A bad O2 sensor will throw a CEL.

I have a CEL
I took it to autozone, they said and shows that I have a MAF error and an 02 error.
My maf is new, and im going to clean it tonight with cleaner that I bought yesterday.
If that doesn't work im going to get an 02 sensor and get that it.
