Fast question about O2 sensor
 

Can I use regular copper wire to extend the O2 lead, or do I need someother wire? Thanks

you should use a sheilded wire and solder and heat shrink the connections for the best possible connection

Well since it's dark, and I HAVE to drive it in the morning I went ahead and spliced in some regular insulated wire and carefully ran it far from the exhaust. Once I get the heat shielded wire I'll do it right. Hopefully this will hold up till then. later

You don't need the O2 sensor connrected to drive the car. It's only used under low-load cruising conditions, and the only effects of not having is working will be small increases in emissions ans fuel consumption.

Just regular insulated wire will do if you mean extending the wire several inches. The SHIELDED wire is for EMI purposes though. Not for heat insulation of the wire. Something like Electrical - Mechanical - Interference.

The shield is grounded near the ECU. The output of the 02 sensor is miniscule and read in milivolts. Even knowing that, I use about two feet of regular insulated wire to mate my 02 sensor to the harness (buggard up harness).

Electromagnetic Interference... ;)

Smartass! Now get busy and give that fine fellow in the other post some SAFC settings. Say a minus 50 across both high and low settings and drive the car at full throttle , up a steep hill, until the knocking goes away. (Sorry MY JUNK, this has nadda to do with your post. Just ignore.)......humor, please.

:rlaugh: u're not gonna give up til he gets what he wants huh?

Ok thanks guys.

I just used regular insulated wire and it's fine.
