just before the catalytic converter
I just spent $425 to replace everything south of the catalytic converter...I think this was a bit high, but I did not have the time or energy to shop around for prices... I just had to replace the entire exhaust on my 1997 Maxima, south of the engine - pipes and cat converter, and it set me back around 1500.
In the exhaust system-it looks like a 2d muffler.
its under the engine aginst the firewall not the by the radiator....
Hard starting, loss of power, poor fuel mileage.
The upstream oxygen sensor is located in the exhaust pipe between the exhaust manifold and the catalytic converter The downstream oxygen sensor is located at the catalytic converter outlet
Hard starting, loss of power, & poor fuel mileage.
Loss of power, hard to start, and poor fuel mileage.
