Most likely a clogged cataytic converter. Remove the 02 sensor. and drive; if better replace the catalytic converter and find out why it may of got clogged. Your prabably not in fuel control and are geting bad gas milage. You will melt the new cat if you dont find out why you melted the first. And sometimes they do fall aprt from age.
