My O2 sensors (I have more than one right...?) are reeeeally dead. I am also really broke. Is this something that would be too hard to do by myself, or maybe if someone helped me? Firestone said it would cost a lot :(

You only need to replace the front one for fuel mileage concerns, unless the rear is throwing a code. It will not affect drivability even if fully dead.

The front sensor can be replaced easier than a spark plug with nothing more than a crescent wrench. Use ONLY an AC Delco sensor.

how much do those ususally cost? (i could research older threads, but this one happened to be right here, so why not?)

They are by far the cheapest even with shipping!

I am currently in the market for one of those things. I have seen them near $50.00.
Mine is rusty as he**.

i may not need a new one just yet...one of my spark plug wires was resting right on the sensor, which i'm told can throw it off, so i'll wait about a tank of gas to see how that affects things. of course, if i do need a new sensor, i won't be able to afford it because i'll need gas

Can we get back on topic? This is Zuper'* topic. Not a free-for-all on everyone'* O2 condition.

Would Denso be an acceptable alternative to AC Delco? They seem to be a bit cheaper. Either way BOSCH is the devil!! Stay away from that one

Denso is an unkown. You wanna test it for us?

If you're asking me, maybe on the SLE. I know it needs one. My focus is more on the other car at the moment...I'll get to it eventually. I know Intense carries the Denso so I can't imagine it'd be bad.
