the o2 sensers on the exhaust manifold are the air fuel ratios mixtures the top senser measrues the how rich or lean the mixtures then sends the info to the ECU then adjusts the ratio to have perfect combustion the bottem one makes sure the mixture perfect. if you want to see if your obd 1 or 2 id look at the bottem of the steering coloem see where the obd plugs in, it should say 1 or 2..
