Im going to replace my 02 sensor on my new engine since i totally raped it while trying to get it out. I heard some things about 'wideband' & 'narrowband' sensors... Whats the difference? Witch do I want? Any other usefull 02 sensor info welcome.

Yes narrow band is what the ECM uses.
Wideband is for tuning, as it's much more accurate/wider range of viewing the AFR. Some Widebands come with a narrowband conversion output box thingy for the ECM and you can run one O2. But I've heard widebands do not last that many miles so it shouldn't be your main O2.sigpic New 2010 project (click image)

As geldartb said, you would use a wideband O2 sensor when you want to get serious about your tune. It's considerably more accurate and has more AFR range than the stock narrowband sensor. Your narrowband sensor is limited to just 14.7 AFR. Most wideband sensors can handle a range from 9 to 16 AFR. One thing to keep in mind is they are not directly interhangable. Yes they both fit the same O2 bung, but they run on different voltages. Narrowband range from 0 to 1 Volts, while wideband range from 0 to 5 Volts. Thus your PCM won't recognize a wideband sensor unless the controller for that sensor has a simulated narrowband output. This would have to be hard wired in place. I don't know of any places that make plug and play kits for this.Your local OBDII moderator

So, if I may digress slightly: I have new Bosch HO2S (AC Delco would have cost $100 more for the pair, and I didn't know better), what symptoms might I be experiencing? Will they die young or will I run rich and get bad mileage or what?'98 Volvo V90 - Ford 5.0 swap in progress
