O2 sensor flakey

[ITSAV6]

I just replaced my O2 with a Bosch, old one was lazy until it warmed a few minutes. New one worked just fine till yesterday and the o2 reads but just drops to 0 mv randomly and it makes it stumble and the wideband jumps to 18:1. I would have gotten the Denso but it's not carried locally. Could it just be something else?

Get the Denso O2 sensor from Rockauto. It will cost you about $14.00 with shipping.

I usually buy 2 so i can have a new spare on hand.

And the Bosch O2 that i bought local and tried just wouldn't work it was so slow,i had used them in the past and they worked ok, don't know what happened but will not use one again.

Agree on denso vs. Bosch

the bosch i took out was 4-5 years old and was just slow, heck my original ac one works better!
