Noise in engine compartment on 2005 Nissan Quest

Recently my catalytic converter was clogged and replaced. However about two days later i started hearing a rattling sound coming from the engine compartment. I also noticed the engine stalls at times. Can anyone help determine the problem

Rattling sounds can be caused by many,many things. How about going back to the shop that did the work for a re-check? Maybe they accidentally left something loose that is now rattling?
