Start by replacing the fuel filter, see what happens.

Good question.

If you have access to a vacuum gauge, verify the the intake path is clear of resrictions or bad air filter, connect to manifold vacuum and warm engine to operating temp. Open throttle and prop open if possible to acheive a steady 2500-3000 engine speed. Watch the reading, it should stay steady once stabilized. If it begins to drop steadily the longer it runs, the exhaust (usually the cat) is restricted.
