so the scanner's telling me ive got bank 1 and 2 front O2 sensors bad but how the hell do you get them out mainly the passenger side? There's no room for anything. Please shed some light on this for me, how do i get to it?

-Thanks

 

get it on a lift, use an extension o2 sensor socket and a breaker bar, or take the midpipe off and use a breaker bar. chances are youll need the breaker bar however you doit, they are a bitch to get out especially if they have been on their for a while. id hose them down with pb blaster too before hand, and you might be able to get away with just a regular socket wrench and extension.

 

Then how do i get to the studs connecting the H-pipe to the headers. From what it looks like everything leads to me having to remove the heders to remove the H-pipe just to remove the damn O2 sensors, is this right? that sucks!

P.S. I'm talking about the front O2 sensors, NOT the rear that are in the open

 

yeah i know you're talking about the front ones.. to remove the h pipe you take an extension and a 3/8 deep socket and unbolt each side. its a total of 4X 3/8 bolts. for the drivers side you will probably need a 3/8 wrench for holding the studs in place while you take the bolt off. the passenger side you will need the bobble headextension and another smaller bobble head extension due to the angle, that will make it plenty easy to unbolt.

 

I see how to get 3 of the 4 bolts off but one of them on the passenger side is behind the O2 sensor
