ok thanks that narrows my problem down and I dont know a whole lot on electrical things but where would this O2 sensor be located would that wire run to the top of my airbox where the air flow meter is!!??


The O2 sensor senses O2 (i.e. oxygen) in the exhaust gas inside the exhaust manifold. So that is a good place to look for it and also one reason why the wires running to it can fall against the hot exhaust. Depending on your smog equipment setup, you may have 1 sensor before the catalytic convertor or a 2nd sensor after the cat as well.
