hey my car has a p1133. I was told this is the pre cat oxygen sensor on the drivers side. So i was looking at auto barn and they have walkers o2 sensors 2 for 40$. I was just wondering if any one ever used these and if they are alright to use. Heres the link to them... thanks http://www.autobarn.net/sophioitem.h...=OXYGEN_SENSOR

 

Didn't say what year or egine, but make sure the sensor is OEM type so that you don't have to get involved in splicing wires. Also, I dislike the ones with brass shells as the soft edges on the hex tend to round off making it a PIA to unscrew it.

 

my cars a 96 z28 5.7L. Is there any brand you suggest and about how much it should cost? thanks

 

Personally, I would go with AC Delco (OEM), and avoid Bosch, being that they never worked properly in my Camaro. Price wise, they are all in the same ball park, depending on who sells them. Somewhere between $50 to $100. Rock Auto lists AC Delco for $75 + shipping.

 

thanks for the info..... are these hard to put in? I thought i read on here that it was easy, but my friends saying its not that easy and i need a certian tool.

 

It is good to get a O2 sensor socket, it keeps the wires intact when you screw the sensor in. About $5 at most parts stores.
