They make a vented vent cap that will allow the air and gases to vent and prevent items from going into the vent stack. Should the vents be left covered or uncovered?

Leave the vents uncapped. They exit outside your home to vent the sewer gases to atmosphere and also allow your system to properly drain. Capping your vents is like holding your thumb over a straw filled with liquid, the liquid won't drain until you remove your thumb.

There's absolutely no problem with using vent caps....As long as they perform as intended. The caps should prevent birds from nesting, or leaves or other debris from clogging up the vents. The airflow from the vents allows the water system to flush and drain properly.
Anyone that's ever had a bird nest in one knows the problem. I imagine the vent cap has a screen or some other protection device that doesn't block airflow in the least. If so, the cap is fine.
For what it's worth, gasses are controlled by the "j" joints in the drain systems. The water standing in the "j" prevents the gasses from seeping back through the drain.
good luck

In many areas it is now law that all drain pipe roof vents are fitted with activated carbon filter vents when a new house is constructed. However, they can be installed into existing systems. Often this is necessary to assure proper "odor free" operation of the vent pipe.

Most vent stacks require covers to meet code here, maybe the same there. The covers do not slow down the venting process and do provide some measure of safety to keep the solids outside, outside. I would put the covers on, but not glue them if you are getting the abs or PVC type. They fit snugly and if you ever need to have the drain lines snaked, you can remove them and reuse them. That way you won't have to but a new cap.

I've never heard of a vented vent cap where I live in Southern California. I suspect they are required by some local codes. You should ask your local building authority. My only concern is that they may reduce the effectiveness of the vent pipe.

IF IT IS A LOCAL CODE, ALL OF THE HOUSES IN THE AREA WILL HAVE CAPS ON THE VENT PIPES. I HAVE NEVER SEEN IT DONE.

Mine are covered. I always assumed to help keep the rain out.
