adjust the idle i think you need a o2 sensor
You have more than one O2 sensor, probably three. They are all threaded into the exhaust at various points.
with your hands and some tools
The O2 sensor after the catalytic converter.
the o2 sensor is located on the exaust manifold
I found this great site about Nissan O2 and its location to fix.. http://maxima.theowensfamily.com/tsb/index.asp?year=2000&tsb=none Search for NTB02-051a All O2 Sensor Replacements Thanks... Jim
They are in the exhaust flow
1995 vehicles did not have post cat o2 sensors.
the upstream O2 sensor is directly below thethe exhaust manifold flanges, above the catalytic converter. The downstream O2 sensor is in the exhaust pipe. Disconnect the electrical connectors and screw it out
On the 2.0 liter 4-cylinder, there is one. On the 2.5 liter V6, there are two.
