Vital, a failing O2 sensor will be indicated by the obvious fuel mileage drop, a rotten egg or sulphur smell, and a premature failure of the catalytic converter. The sensor will RARELY throw an SES light. Only a complete failure will do that. The sensor will get 'lazy' after about 50-60k miles.

My O2 from Bosch lasted less than 30 days. Jr's3800 had a similar experience. My AC Delco sensor has been in for over 20k miles now, and doing fine.

Thanks Bill....I will closely monitor for those symptoms.

If you leave the brackets mounted to the strut tower and just undo the 2 bolts on each side that fasten the bar inplace, it will not cause any problems. Its when you move the brackets that you can skew the alignment as it is the strut mount bolts that hold the brackets on.

On the 96-99s it is easier to drop the bar, as there is more clearance between the bar and the master cyl.

Yes, that'* exactly what I was referring to. I've never removed the brackets, just the two bolts at either end of the bar.

You might want to dab some Dielectric(Silcone)Grease inside of the spark plug boots. I use a Q-tip to lightly coat the boot socket. This will make it easier to remove the booty the next time you need to replace your spark plugs.

The thing about a name brand Co. like Bosch who claims to have invented the 02 sensor
is if you get a failure you go to them and you are sure to get satisfaction.
Thats what I would do if any of their products fail on my Bonnies. Especially
if its prematurely.
