my mechanic says it might be that since the thermostat may be stuck in open position, the catalytic converter may not be registering hot enough to work effectively. Is this possible??

    90% it's a stuck open thermostat. Have the mechanic plug in the scanner and see what the coolant temperature is getting up to. Should be above 190 degrees while driving.
