i ran it for about 20 minutes before getting the test. so now how would i go about checking if my O2 sensor is bad?

 

you just answered your own question.

the ECU set your code because it was detecting something wrong with the o2 sensor. so because it never came back on after that it doesn't mean the sensor fixed itself. there is something wrong with it. it's probably contaminated.

if you took your multimeter and measured the output signal of the o2 sensor I'm sure it will give you some weird readings........

change the sensor and retest the car......

 

how easy is it to replace hte O2 sensor by myself? anyone else had any experience doing this? i found a Standard Auto Parts O2 sensor for 150 online, sound like the right price?

 

Plus how many O2 sensors do i have? Since im ODB1 is it just one in my exhaust manifold?

 

$150 is about right for a generic sensor. Did you check to see if it'll work with your car?

And you are correct, you only have one oxygen sensor which is mounted at the collector of the header.

 

I found a Standard Motor Products Oxygen sensor, Upstream sensor, Vtec Engine for 170 or so, is that a specific fit for my car? Im a 95 tegra GSR. ACDelco Oxygen Sensor for B18C1 costs 98, and then their are some Universal Oxygen Sensor, Sensor Kits, B18C1 for like 65. But what is a sensor kit? and how is it universal if it is for B18c1? Can anyone shed some light on this for me?

 

I believe a "universal" kit requires you to cut some wiring off your old sensor and splice it onto the new one.

If you want something that will be a direct fit your best bet is to get something from a dealer. One such place is acuraautomotiveparts.org where it's I believe $180 or so. They're a dealer that sells parts online.

Otherwise NAPA has a bunch of options, the most affordable being a Beck Arnley direct fit sensor for $129.

 

Fats, you are that smart, must be the double fisted slamming of Red bull you have been doing :beer:

 

would a bad O2 sensor cause my engine to bog down? cause i bought a new cat thinking that was causing my engine to bog yet i still bog down. would a bad O2 sensor cause this?

 

There are any number of possibilities for the engine bogging down, the o2 sensor could be one of them.
