Are there any other good o2 sensors out there, like Standard motor products, niehoff, or beck/arnaly? I would get one from gm direct, but I can't wait that long on shipping.

Denso from rockauto.

They ship very quickly.

Thats the one I got now and its not doing a good job anymore.

Ok..but was your car running poorly and that damaged it?

Heck..if you want quick and cheap..take an O2 socket to a JY and pick up a couple for $10

the denso was running fine for about a month and a half then my mpg started dropping. The denso is about $26 at autozone and I just thought that since standard motor products cost $32, they may be better. I looked a topic on here about a debate that some of bosch are denso. And also that standard motor products supplied AC Delco'* o2 sensors. Don't know how much of truth this is, but it'* in a topic around here somewhere.

After trying a Bosch O2 myself and finding what everyone says was true I went back to a AcDelco.

Amatter afact I went to the dealership to get one. They told me it was $133 plus tax and I told them "I am going to buy it else where." (I was about 5 seconds away from telling him I was going to buy it from Intense-Racing.) Then the guy at the parts desk said "hold on Sir, let me see what I can do for you." He ending up coming down on the price to about $94, so we had a deal then

Call John at RMS Auto Parts (www.rmsautoparts.com) in San Antonio. 1-888-658-4675. I know they stock those (either AFS20 or 21) quite well, and you won't beat their price. Just get it overnighted.

I'd wait a day for an AC Delco rather than throw in anything else.

iight I guess I'll wait thanks for the help

That is still WAY to much. I got mine for HALF that at a delco parts dealer.

And you had the single wire..not 4 wire.
