o2 sensor questions
What should the o2 sensor read out be at idle, what o2 sensor should i buy that would be a cost efficient yet reliable replacement sensor? If buying a heated o2 where do you tap into a power sources for the third wire?
Thank You

The people that I've seen replace the O2 sensor also use the Bosch replacement, which you can pick up at most local automotive shops.

ok since no one else is helping...idle it would vary...the o2 dosent become warm enough to read untill abt 5 minutes of driving so you have to drive it then see the reading @ idle. on my car it would vary from stoich..to full lean then majority of the time it would read 1 bar rich...
the heated o2 is not nesicary unless you plan on running leaded race gas..all it does is gives you the ablity to pre heat the sensor so the lead cannot deposit itself on the sensor material...to run it you have to make a circut for it...runa fused power wire off the bat and either relay it so you can use a small swich in the cabbin or b use a larger swich under hood but you have to manualy turn it on and off, unless your decent with electronics and know how to wire a relay into a swiched circut..this way it could only be on when ignition is in the on position..-just incase you forget to turn it off
but in all honesty o2 gauges are just disco lights for the car, stock (ie not lamda) sensors are trash they cant read acurate enough to let you know when its going wrong only when its 2 late,..a EGT is a better way to be shure
hope that helped

To add to what Bacon said, just buy the cheap-o Bosch generic at your local auto parts store. They work just fine. Don't waste your money on the heated ones.
