    Range Rover Classic
    Today, I got a new O2 sensor from a RR parts supplier. It has "Z27-24E" etched on the body. I wanted to bench test it prior to installation, as I put 2 new ones in from another well regarded RR supplier and one sends a signal and the other does not. I used the heat it with a propane torch...

    Well this is a lovely safety hazard! Lets hope i don't roll it on its side and can't get out! How do I get the door open to work on it? The vehicle starts and operates normal; I assume this means i'm not superlocked, therefor why can't I pop the door open by leaning over and pulling the...
