Hello mrsalbert, my name is JShreader. Thank you for choosing fixya.com

Depending on which oxygen sensor you are looking for...there are several of them throughout the Exhaust System. I will start out by giving you a brief description of what and oxygen sensor is, and they're general purpose.

DESCRIPTION
Four Heated Oxygen Sensors (HO2S) are mounted in the exhaust system where they monitor the oxygen content in the exhaust stream. There is an oxygen sensor mounted in each exhaust manifold and one on each end of the catalytic converter. the oxygen sensor located in the front exhaust manifold is the Bank 2 Sensor 1 (Front) sensor. The oxygen sensor located in the rear exhaust manifold is the Bank 1 Sensor 1 (Rear) sensor. The oxygen sensor located in the Y-pipe ahead of the catalytic converter is the Bank 1 Sensor 2 (Pre-converter) sensor. The oxygen sensor located in the catalytic converter outlet is the Bank 1 Sensor 3 (Post-converter) sensor.

OPERATION
An oxygen sensor acts like a battery because it creates its own signal voltage once it reaches operating temperature. This voltage is produced when the oxygen content in the exhaust stream is different than the oxygen content in the atmosphere. A lean condition (high oxygen content in exhaust) will produce a low voltage (near 0 volts) and a rich condition (low oxygen content in exhaust) will produce a high voltage (near one volt). The PCM provides a reference signal voltage (0.45 volt) and a ground to the sensor. The PCM reference voltage is necessary because the oxygen sensors do not provide their own voltage until they reach operating temperature.

HEATING ELEMENT
the oxygen sensors also incorporate a heating element inside of the sensor housing. This heating element is energized with the ignition On and allows the sensors to reach operating temperatures quickly. The PCM can then use oxygen sensor information sooner after engine start-up.

PCM INPUTS
The PCM uses oxygen sensor information during Closed Loop operation to constantly adjust fuel control to reduce exhaust emissions. Because the oxygen sensors provide information sooner after engine start-up, exhaust emissions are reduced. Faulty oxygen sensors will cause various driveability conditions and will set a DTC.

That being said...I uploaded a .pdf for you of pictures showing the locations of ALL the oxygen Sensors on your Vehicle. You can download it by clicking HERE.

I hope this helps you. If you have any more questions or need any more diagrams, please don't hesitate to ask...Thanks again, JShreader!

The Fuel Filter is located: Under vehicle, driver side, below seating area, driver side of fuel tank, mounted on frame in fuel line.

Here is the replacement procedure. Hope this helps
Lefty64

WARNING Fuel supply lines on all vehicles equipped with fuel injected engines will remain pressurized for long periods after engine shutdown. The pressure must be relieved before servicing these fuel systems.

  1. Disconnect the negative battery cable.
  2. Depressurize the fuel system.
  3. Remove the filter bracket retainer.
  4. For plastic type fittings:
    1. Grasp the filter and one fuel line fitting. Twist the quick connect fitting 1 / 4 turn in each direction to loosen any dirt within the fitting. Repeat for the other fuel line fitting.
    2. Squeeze the plastic retainer release tabs and pull the connection apart. Repeat for the other fitting.

  5. For metal type fittings:
    1. Use a fuel pipe quick-connect separator J37088 or equivalent. This is available from your local parts store.
    2. Insert the tool into the female side of the connector, then push inward to release locking tabs. Pull the connection apart.

SOURCE: where is 98 eldorado cadillac 4.6 starter located?

It is located in the valley between the cylinders. You can loosen the throtle body, all the bolts holding the intake manifold and then lift the manifols just enough without disturbing the fuel rail to gain access from the lest side of the car to the right. This can be done with common tools and the gaskets on the manifold and TB can be reused if not damaged.

No power hesitation


Did you replace the fuel filter ? There is NO WAY TO CHECK a fuel filter. Because fuel comes out of the feed side of the filter does not mean its not clogged. It could restrict under pressure. I say , start by REPLACING THE FUEL FILTER. There is also a screen in the tank attached to the pick-up. It also gets clogged at times. Hope this helps.
