O2 Sensor From Hell... Post your war story and solution HERE.

C'mon, no one here has changed all 4 oxygen sensors on their VX? Amazing...

I may be looking into changing a few of mine this or
next week...
crawled under mine today, located them all..
if you have the correct tools, its not as bad as it looks
really. They make special O2 sensor wrenches and sockets
for harder then most sensors to get to.
Matco and Snapon both offer their share of "specialty
tools" .
The one on the pass side you can get to the plug from
the top, its not that bad, just follow the wire up and youll
find it.
A crows foot may work too on getting them loose too
just be sure not to round off that sides, that happens alot
if they are stuck in there from age.

Keep me posted of your progress.

I did deploy tools you suggested in my attempt, however in spite of having the proper tools the cleareance was to small to operate the offset O2 wrench in the space provided on the VX for the passenger side front sensor. I am sure there is a way to do it without removing the passenger side cat, but can see no other sollution at the moment.

I gained 3-5 MPG by changing out 3 oxygen sensors. With todays gas prices it is a worthy project. It also eliminated the occasional hesitation issue as well.

O2 sensors around $75 dollars each. Are there some cheaper somewhere?

I found them on a site for around 35, but my home PC is down and that's where the link is...
I need to swap my rear 02's out, so I will be making this a priority soon. I will keep you all posted.

I have a confession to make... I changed the 2 easy o2 sensors because it was running rough at idol only to find out after that the plug to the air flow sensor fell off! glad I didnt cut the pipes to get the up flows......I feel better now
