This should be the O2 sensor on the passenger side, after the converter. Its job is to report to the ECU on exhaust after passing through the converter, so has no effect on the way the car runs, but just reports on how the converter is doing its job.

They should in the exhaust pipes just before the catalytic converter

check your spark plug wires and coils

Not usually, but O2 sensors have about 60 to 70 thousand mile life spans

Hello degarmo1960,

Below is a wiring diagram showing the idle air control.



I hope this helps.

COULD BE WEAK FUEL PUMP WEAK IGNITION SYSTEM CAUSED BY A BAD COIL CLOGGED AIR FILTER..CLEAN FUEL INJECTORS SEE IF IT HELP.IF NOT YOU HAVE LEAKING INTAKE OR LOW COMPRESSION CYLINDERS.CODE SCAN FOR FAULTY TPS SENSOR.

the only sensor that would be on your manifold would be the o2 sensor ihave an intrepid i have four, two converters. 1 before each converter and 1 after each converter. fronts are 1s and backs are 2s all are 4 prong maybe your backs are threes you will need to investigate a little more after all we are dealing with pretty much the same car same year

The #2 O2 sensor should be found "down stream" from the catalytic converter. When you crawl under the vehicle, follow the exhaust pipe from the engine to the catalytic converter. Right before the converter, you'll see one of the oxygen sensors. (That's number 1.) When you follow just past the catalytic converter, you'll see another one. (That's number 2, the one you're looking for.)

The role of the #2 O2 sensor is to make sure not only that the #1 sensor is actually doing its job of maintaining a 14.7:1 air/fuel ratio governed by the computer, but it's also making sure that the catalytic converter is not only present, but also that it's doing its job as well.

This isn't a very expensive part, it's easy to find, and will require an O2 sensor socket to do the job. Make sure you don't use any grease on the new sensor! It can actually render it unusable and cause your check engine light to come on again.

That reminds me...When you change out your #2 O2 sensor, in order to turn off the Check Engine light, you'll need to take it somewhere such as an auto parts store like Advance Auto Parts, who have a scanner to connect to your car's computer and clear the fault code. Otherwise, your computer will have to count a certain amount of ignition cycles before it determines that all is well with your emissions system.

Good luck, have fun, and I hope this helps! :)

check your timing belt and make sure the timing is on right

ASE Mechanic:

Sounds like a sensor problem. try cleaning the MAF sensor, those get dirty from not changing the air filter and cause havoic to the air fuel ratio.
