PS: if the O2 sensor is not there in the picture, please show me another if you have one please

The O2 sensor is on the downpipe on the passanger side of the engine bay.

Here is a link to the A/F install write up.

You are looking at the wrong side of the engine bay.....

The O2 sensor measures your exhaust gases....it's in your downpipe/pre-cat.

Also, I've heard that splicing into the wires at the sensor is a bad idea and it's better to splice into it at the ecu. I wouldn't know because, to be perfectly honest, an A/F gauge that reads off your stock o2 sensor is about as useful as tits on a chicken.

About the only thing it will tell you is if your o2 sensor is good or not. At cruise, it will bounce between rich and lean. That's about the extent of it's usefulness.
