94 V8 -Check engine- O2 sensor?

[lukeheller]

My check engine light has been on for some time now and I've been to autozone and had them hook up their computer and it says that I have a bad o2 sensor. Should I trust and and just change the sensor? Someone suggested that I may just have a vacuum leak. If I do need to change the sensor, how do I change it. I haven't been able to find that sucker.
Thanks

how is the car running? any hesitation or power loss? those code readers read exactly what the computer has registered as the problem. if its calling for a O2 sensor code and reads something along the lines of (bank1 sensor 1), thats when you will know its definately an o2 sensor problem. if there is a vacuum leak it will usually let you know if thats the case.

fwiw, o2 sensors usually only last about 50-75k miles depending on how the car is cared for, which octane fuel is used etc etc. if ur up there on miles, above 50k id definately just swap the o2 sensors out, they'd be past due anyways. also change the fuel filter while ur at it too.

if you need help walking ya through the steps to remove the o2 sensor (s) pm me here or hit me up on aim, Urbrightestdark is my screen name as well.

Good luck meng
