1997 Other Mitsubishi Models O2 sensor

Your MAF should be between the original airfilter and intake manifiold, usually located on the connecting tube between the tube and the manifold. You will recognize it as a flat square box with a female end on it and a bunch of wires going into a male adaptor which plugs into the female end on the MAF sensor. Your O2 sensor is found on the downpipe, most likely before the catalytic converter, you will recognize this as it sort of looks like a fat spark plug with a wire coming out the ttop. (Maybe two, maybe three, my TT 3000 GT has a four wire set up)
