02 sensor?
Okay I own a 1989 Honda CRX Si, with a JDM D15B SOHC VTEC swap, anyway my car runs rich, i can smell the gasoline when i drive and i am definately not getting as good of gas milage as i should be. I was told that I should get an o2 sensor and reset my ECU. So I have a few questions.
-are 02 sensors CAR SPECIFIC?
because I have one sitting in my desk droor just not sure if it will work on my car , its a bosch 02 sensor.
-How do i reset my ECU and tell if it is obd-0 or obd-1?
-how much should an 02 sensor run me?

Re: 02 sensor? (v8Buster)
FWIW, I had tried the Bosch generic O2 sensors in the past with poor results. I ended up going with the OEM type. At the time, for my single wire type sensor, it was around $160. Resetting the ECU is not necessary after replacement.
O2 sensors have an effect on the air/fuel ratio, but I don't believe a nonfunctioning one would cause a raw fuel smell. The engines run in open loop until the sensor heats up enough, and I have never noticed a gasoline smell during that period. You've probably got other things going on too. Injector stuck open or shorted to ground?

I wouldn't pay $160 for a single wire.. doesn't fit into perfection for me..

Ouch! Is that a slam?
After wasting enough of my time on 2 cheap generic sensors, I just wanted something that worked. Actually it cost more like $140, but it was for a Honda OEM sensor.
He can reset the ECU, but in my experience it is not necessary, unless there is a code you want to clear. The ECU constantly adjusts to the O2 output anyway, so there is nothing to gain in resetting it.

-I don't think the sensor itself is car specific but the plug at the end of the wire might be.
-To reset the ecu, just pull the ecu fuse from the engine bay for 15 mins. Your car is OBD0 unless you changed it to OBD1.
-Depends on the brand and where you get it. I've heard bad things about Bosch o2 sensors.

slam..no... just stating my opinion.. didn't say yours was wrong..
i just like to reset my ecu too often maybe... atleast every time a season changes.. or I make make a change to the car thats involves electrical components..
