Question about 1984 Buick LeSabre
Well, with your description, it seems that your car was running properly before, but is that really the case? Why was the timing chain replaced? Was there a problem?
So, did the timing marks line up perfectly? did you reset the ignition timing?
Really, you do not want to remove the catalytic converter, ever. It is a key piece to maximum performance. Not racing performance, but the best that your car can be...
If your engine malfunctions for an extended period of time, the converter can be damaged, but fix the problem, and replace the converter.

Catalytic converters tend to act up at high volume output or higher rpm values same for inadequate fuel pressure it wil perform well at lower rpms and lower power demands but as soon as the rpms or throttle demand increases beyond a certain point the car will bog or lose power, or in your case doing the chain you may have the timing chain off one tooth, check this by bringing the engine to Top Dead center firing stroke line up the timing marker on the front crank pulley with the pointer and remove the valve cover if on number one cylinder ( or front two valve rocker are under no pressure ( you can phsically move them them your ok, if not re set the mechanical timing you did the job wrong.
