    what one member did was take out all sensors and extended the holes of the stock sensors with a needle nose plier..try that ..plug them back in ...drive it for a couple days..then check for codes...see if it works

    they may not have the same part number but are the same, they will work. i know lots that put rears in fronts. its just a different part number from the lengh of wire i think. PO155 is for the pass front.

    its a bitch to get off let me know how you do

    correct..you can move the rears up to the front unless you have a vette. I think the vette has different front connectors if I remember correctly. What exactly was the code? I see where he said 155 but I don't see where you said that's what it was. Do you have headers?

    O2 codes just come with the territory with LT's usually. Usually heater codes but lazy codes will come with them too sometimes. I just clear them and go on mine. I have bosch 13111's in the garage I'm gonna try this time around. Some people have had luck with those getting rid of the heater codes while others seem to have no luck at all with bosch sensors. Figured I'd give them a try and see for myself.

    from what i heard the vettes will work fine and most of the time there prefered bc they are a lil thicker in the casing, but that just chat room talk. you probly know best

    yup, you're talking about the vette rears. Those are the 13111's I have in the garage to put on next to try out, the heaters are supposed to be a little better because they're the rears for the vette. I've read mixed results with them and wanted to see for myself.

    usually you'll throw a code if they go bad but not always. Sooted up exhaust is one way to tell but even that isn't always completely accurate. I found a buddies bad O2 by scanning the car and saw one O2 was flat lining at 450mv.

    well on drivers side abouve your right leg there is a inlet port that is a gateway to your ars computer. all you do is have autozone hook it up with the key on, but not started and if there is any codes it wil come up on the code scanner

    its a nice tool to have if you do it all the time but if you rarley get codes like most people/cars , autozone does it for free. .
