I have a 93 f-150 302 and whenever the truck gets up to operating temp. it starts to smell from the exhaust. Is this the sign of a plugged cat or something else.

Does the odor smell like a rotten egg? If it does, then what your smelling is sulfur in the catalytic convertor. In other words it should smell like that...

try changing the ECT sensor {coolant temp sensor,not sender}.You could be suffering from over rich or lean fuel mixtures.might even turn off the check engine light.
