Oxygen Sensor Causing Power Loss???

[rpeterse]

I know that I have a bad oxygen sensor. Lately my 2001 outback wagon has been losing power unexpectedly. Could this be linked to the bad sensor? The loss of power occurred early on at lower speeds. Now it happens all the time. It also stalls at stop lights. Today I smelled burning rubber coming from the engine. However my check engine light is not on. Any thoughts?

Well, O2 sensor issues can cause poor mileage and throttle response/power........but if you smelled burning rubber you may have a timing pulley seized, or other timing belt issue and youre belt is about to let go.

 

I would suggest having the timing belt checked before even attempting to start the car once more

 

Not to scare you too much, it is simple enough to inspect by removing the radiator fans, the Alt and A/C belts, the crank pulley, and then of course the timing covers. You should know quickly once the covers are off if there is any problem.

 

If you have the money, you may want to install a new belt now even if OK, as you are about %90 there already.

 

But seriously, check or have it checked.

Gloyale makes a good point. Is your smeller accurate enough to narrow it down to the front timing belt covers/crank pulley area?

 

Good luck.

Thanks for the suggestions. I will look into it today and see what I can see.
