O2 sensor replacement instructions and torque specs needed

Good morning,

I attached 2 pictures for you of the location of the sensors.

They are torqued to 18-foot pounds of torque.

The front sensor is on the exhaust manifold. The rear sensor is downstream of the converter.

You need a 19 mm O2 sensor socket for the removal.

Do not go cheap on the sensors. Aftermarket cheap sensors do not respond well. Try to keep to the original equipment sensors.

The VIN number is: 3n1ab61e38L719837.

It's also got a p0300.

I attached the possibilities for you below for the misfires.

In most cases, you will need to check the fuel pressure to be sure the fuel pump is providing the correct pressure. I posted the pressure required below. You can rent a tester at a parts store for the test. If it is low, the pump will have to be replaced.

Fuel Pressure
Fuel pressure at idle .................... Approximately 350 kPa (3.57 kg/sq. cm, 51 psi)

The fuel pump can be changed by removing the rear seat bottom cushion to gain access to the cover for the fuel pump.

And can I get the intake specs and throttle body and all that for this too? Because this one looks different than what is provided.

I attached the intake and the throttle body specs for you below.

Roy

The O2 sensor you have circled it shows bracket is 18 ft pounds and the sensor is 37. is that right?

Correct.

Roy

Would a air fuel ratio sensor bank 1 cause a random misfire in 2 or more cylinder?

I doubt it very much.

As I stated before, I would verify fuel pressure. Low fuel pressure from a weak pump is the most common failure for that code.

Roy

Oh, okay. thank you so much .

You are welcome.

Always glad to help.
