I got an o2 sensor off of amazon. it says it fits my car. as im looking at the picture over the internet, i noticed the plug in is round... is this a mistake? i also found an 02 sensor that looks like my stock one, it says that will fit too. not sure whats up with that.

 

Most pics are not the actual item you are buying. I've seen those, time will tell.

 

Your car uses two four pin flat O2s. The round (or square) connectors are for the rear sensors on a dual-cat car.

And why on earth would you order oxygen sensors off of Amazon?

 

because amazon is 25 dollars cheaper

 

So I suppose it's okay that they are cheaper but they ship you the wrong ones.

 

well it wasnt wrong on there part per say. it was dumb of me for ordering that one. i didnt know these cars could have different 02s for the thing you were talking about. and at the time of order i never saw the ones they are showing now. kind of makes me mad. now i gotta wait til these get here, pay shipping and send them back then get the right one...

 

What brand are the Amazon sensors?

 

AC Delco is the brand inj. i was just angry that i have to send them back. i need to get this thing running down the road
