2001 Nissan Maxima 6 cyl Wheel Drive Type unknown Automatic 99800 miles

First, I'm wondering how many catalytic converters are on my 2001 Nissan Maxima? I have been told there are two by one mechanic and three by another. I have been told that they need to be replaced. Do I need them ALL replaced? How does a mechanic check to see which one may be giving me problems? My car seems to be bogged down when trying to accelerate, sometimes it won't speed up at all when I press the gas pedal completely to the floor. This is especially the case when my car is still cold or when trying to climb hills.

Thank you.

Do you
have the same problem?

I belive there are two on your vehicle. They can be found out if they are bad by a digital pyrometer, or by the o2 sensors located after the catalytic converter.

Or he may decide to hook up a vaccum guage and idle the car at 2500 rpm's for a few minutes and if the accellerator is constantly being pushed to maintain the rpm's or the vaccuum slowly but steadily goes down, then you have a restricted catalytic converter.
