Well, hard to diagnose over the phone, er internet.  Easy way to see  
if it's actually only running on 4 cylinders is to unplug the coil on  
the drivers side and passenger side alternately.  It should run on  
either side. If not, you may have a coil/distributor cap/rotor  
problem.  This should be remedied immediately.  It may be too late  
and you may have melted one or both cats internally.  He didn't go to  
the do-it-yourself carwash and powerwash the engine, by chance?

Good luck.
