where is the oxygen sensor located on a 2000 gmc jimmy ?

i could be wrong but it beleive it to be just after the cat.

do you know if there is only one?
she is running real rough.

yea. mine is an s10 and i changed it awhile back and it helped out a little but there are many other things that can equate to it running rough. first off i'd changed oxygen sensor(o2 sensor) it is actually expensive if i remember correctly. this will cut down the other things causing the rough idle or running.

well I notice that it did fine until the temp came up. then noticed that the temp never cam down. I just flushed the radiator last night and replaced the the thermostat . there is a lot of rusty water in the radiator again today. I think I will have to spend the 200 for the radiator. it might not be the sensor.

Well, I know in a S10 there are two o2 sensors. The one after the cat does not effect fuel / air, but the one before the cat does.
The one after the cat only tells you if your cat is working properly.

With my 96, I had 4 O2 sensors. 1 each on the left and right just after the exhaust manifolds. 1 pre- catalytic convertor, and 1 after the cat.

This of course is with the 4.3 v6. I would assume this is the same for the 00's as well.

I would try flushing the cooling system again also....hell, it's cheaper than a radiator.
