...again, am like a broken record here, it's the EGR valve, what takes exhaust gas and puts it into the intake manifold under decel and/or specific conditions, gets messed up with carbon and frequently has a leaking vacuum control hose~ take it apart and de-carbon it, or buy a new one~

Could be something dealing with the ignition timing. Where it will run good but no power. Vacuum advance if it has one.

Did the cat melt down? If it did then it may have plugged the muffler. Have you had an exhaust backpressure test done?
