Default Intake vaccuum port?
My 96 B1500 3.9L is running poorly when warm. I noticed there's an open port below the PCV port. Can I get some help identifying what is supposed to be there? I found nothing in the service manual.



Note the open port is the lowest of 3 in the area.

If you plug it off does it run better?

Could've just been a cap that cracked and fell away.

It does run better when plugged. It seems to idle high and unsteady when unplugged.

Can anyone show what a cap is supposed to look like? Otherwise I'm tempted to use a little stopper.

Thanks for you thoughts.

Just plug it with whatever you can plug it with.

Just about any auto parts store has an assortment.
