99 Nissan Quest engine idle problem at stop

I Have a rough engine idle at stop lights. Checked : catalytic converter, had all the belts replaced including timing and water pump.
Any suggestion appreciate.

things to consider: O2 sensors . motor mounts. inspect spark plugs - are all cylinders firing?

Here is a link to the full dealer service/repair manual. Not Haynes or Chilton, service/repair manual. Very comprehensive. Perhaps you can find an answer there.
