Point of O2 sensor?...

[calimus@techography.net (calimus)]

Why disconnect the O2 sensor to check dpr, I dunno about that.

Disconnecting doesn't cause any difference in running, sounds like a bad O2
sensor

Power loss after driving a bit, could be the O2, if it's bad it sends the
system into limp home mode, basicly causing you to run lean if I remember
correctly.  Running lean will cause a lack of power.  There are other things
that can cause that as well (hall sender comes to mind), but I know when my
O2 went I was having similair problems and after replacing it, I got power
back.  I still need to adjust the mixture since now I'm running a bit rich
and my low end tourque isn't too good.  Then again, my engine has over 200k
without a rebuild so I don't epect much at low end either, heh.

> 16V questions:  I thought the O2 sensor was to help the DPR determine fuel
mixture, but Collin from TT told me to disconnect mine in order to see if it
is working... Disconnected, the car doesn't run any different, so what's the
point of the O2?
> And while I have your attention, anyone know of what would cause low
power; electrical related - i.e., after a little while of driving, power
drops off badly.  Turn car off, turn car on, problem's gone for a little
while...  Knock box and knock sensor have both been replaced.  Would coolant
temp. sensor do this?  Coil?
