O2 Sensor help..
I have code P0135 and correct me if Im wrong thats the driver side front sensor. Well I have LG Pro Lt's and have no cats and no rear O2's. I have it tuned so I know thats not the issue. I checked the fuse also and the fuse is good. So Im down to replacing the O2. My question is do I use a rear O2 for the fronts cause they are better? Or do I use a original front O2? Thanks!

They are different part numbers for whatever reason, therefore they are different for that same reason. Personally speaking, use whatever is called for rather than trying to change things.

rear 02's have a better heater; and many who go to headers (with only one pair of sensors total) will use rear sensors in the frontwards locations. I do believe there is a connector difference; but i'm certain I've read that someone has a work around for this.
I imagine someone will reply with actual experience & more correct info.

Ever since I had my headers installed, with two hi-flow cats, I get these codes:
P0420 and P0430. I believe they are related to my rear O2 sensors. I still have all four installed.

The front connectors are a flat 4 wire, the rears are a square 4 wire. A lot of header vendors sell a converter to connect the rear O2s to the front. Be very caeful with the execess wire, having melted wires is a leading cause of issues.
Also, the front O2s have a short wire on them. If trying to install on long tubes they may not reach.
Not sure how true the better heater argument is, but it definately will reach the O2 bung on LT's.
