Is my engine low on vacuum????????????? Help?????

I took a long shot and googled "2103 PCV" and came up with this cross-reference listing:

So it crosses to a Mopar 3671076, which looks like a plain-jane Mopar PCV, and I suspect it is wide open at idle in your engine, and not at the lower idle flow level. BTW, if it is open to the wide open cruise flow at idle, you can pull the pcv from the valve cover at idle, still connected to the hose to the carb, and if it has a loud 'whooooooosh' all the time, then it is wide open. In that case, put your finger over the open end and the vacuum should jump up a couple of inches.

The 4343581 crosses to a 2193 in the same catalog, and that shows it is for some mid 80's cars & trucks. Odd....Here is a thread that discusses the FV191 and 4343581; just filter through the nonsense LOL:
Good quality PCV valve

OK on the secondaries being all closed; I was just making a guess based on what we found. If excess PCV flow is closed down, then I bet you can/should open that secondary up. You'll know you are doing good if the idle mixture screws are more effective. It may take a few tries to get the secondary transition smoothed out.
