quick question about the O2 sensor
#3
Is it NEEDED? Well I have been driving with a broken one for the past week (installing a new one today) with no apparent affects. If I didn't have a A/F gauge I would never have known it was broken.

The o2 sensor isn't needed. Is it better to have it sure because you get much much better gas mileage, but i drove without one for about a month and saw no negative side effect besides the gas.

You can see it on the passenger side exhaust manifold. IIRC, it leads somewhere close to the rear of the manifold. Without, it runs rich can cause damage to the cat, backfiring, etc. It's time for mine too :-)

look, just run a wire from the o2 sensor through the firewall in the pass. side of the car. pull up the carpet and look at the ecu. patch the wire into slot D2. that will be the second largest connector. Its the second wire from the right on the bottom row.

the wires run in alphebetical order if you pull out the harness and look at it from the connector side. I didnt pull it out and instead just reverse the alphabet like i show above.
