Re: 02 sensor

Blue smoke means you're burning oil. What brand O2 sensors are you using?

Re: 02 sensor

bosch i think they suck but thats they had

Re: 02 sensor

Yeah. Bosch O2 sensors tend to not last long and don't work very well in the meantime. I would suggest you try Denso or AC Delco 02 sensors and stay away from the Bosch.

RockAuto has them for a good price if you can't find any.

Re: 02 sensor

wats the part number they all similar dont wanna order the wrong part

[ssms5411]

Re: 02 sensor

Part # is in the post AFS75 for the front O2's. As long as you have the flat connectors and not the square type for the rear O2's.

I came across this website looking for AC Delco O2's, price seemed to be good so I thought I would pass it along, I just ordered 2 of the AFS75 for the front O2's, I was starting to get a low reading in bank 1 the drivers side, it wouldn't go past 900. Here is the website: www.getgmparts.com
