Sounds like you have a tight house. And don't have enough make up air for your stove, and or oil stove.furnace.

Add a make up air vent.

In order for the wood or oil to burn. It needs air. That air comes from your house. After so much is burned with teh fuel. New air must come into the house to replace it.

in your home. that new air is coming from the opposite chimney. So you need to provide another way/method for the air to be replaced. Its known as make up air, or combustion air intake.

Install an intake close to the wood stove.

Where is the stove located.

A small intake. Probably a 6". Terminated near the stove.
With either a damper you can shut off when not using the stove.

Some people, just open a window an inch or so.
