58663, Do I need a new O2 Sensor???
Posted by gilee_8, Oct-15-03 10:57 AM
Sup guys..
Ok...I installed my A/F gauge..and I am starting on the fuel system and so on....
And I have alot of questions about how to install SFMU on my 1995 eclipse GS. (any ideas?)

Ok.. my second question is... Do I need a new O2 sensor?
From the reading of the gauge... it jumps up and down from .01x to .9xx at idle...and when I drive... it jump up and down from .01x to .9xx or sometimes 1.1xx.... or .005...SO LOW! and SO HIGH!

I thougth it should jump around at .5xx????
Look at this movie clip and let me konw if my current O2 Sensor is FXXKED!
THanks.

That's normal. Though I'd check your ground ... shouldn't be getting numbers in 1.1xx. Find a better ground.

Exactly what it is supposed to do. If it holds still for a long period of time (other than .9X at WOT), expect your CEL to come on shortly.

Also remeber unless you have that A/F guage set with a wideband o2 it will not give you accurate readings. So do not try to tune your vehicle with your A/F guage until set properly with WBO2.

Switching O2 dsensors are perfectly accurate - at roughly 14.7:1 A/F. Anything too much to one side or the other and it'd could be off an inch, it could be off a mile. Thw point of it isn't to try and hit a specific A/F ratio - the point is just to make sure you are sufficiently rich at WOT. It's not ideal, but it's certainly not a $1,000 UEGo.
