Yes, if the timing was not set properly when replacing the belt then the exhaust valves open at the wrong point in the cycle. This will cause the catalytic converter to be dealing with gasses that are outside of the normal parameters. Either unburnt hydrocarbons or the valve opening before combustion is completed, either way it will get very hot, and potentially melt the innards and potentially plug the exhaust.
The timing mishap can be due to the cams moving when you removed the old belt, or the new belt not being put on in the right order so the slack ends up at the idler pulley.
What else can I help you with?
Can bad engine timing make a catalytic converter go bad?
Yes, the unburnt fuel from poor timing will enter the converter and slowly destroy it.

Can you take your catalytic converter off of your 2000 dodge ram 1500 without negatively altering your truck?
No, the computer will turn the check engine light on and adjust the fuel and ignition timing to a default setting which will change power and economy. It is also illegal to remove a converter without replacing it with a new one.

What causes a catalytic converter to turn red hot on a Ford F-150?
Fuel mix is too probably way to rich, the catalytic converter basically reburns incompletely burnt exhaust fumes. Check air cleaner and carb/efi system and timing. If timing is out check for stretched belt/chain. Inaccurate timing will cause fuel to be incompletely burnt and performance will suck.
Your 1991 Chevy caprice has no power at all is it the fuel pump the filter was changed 4 months ago im thinking its either the fuel pump or filter?
