There is a vacumn line to the air cleaner which in turn has a temperature sensitive mechinism in it, of some sort.

That item could be a THERMAC door and heat stove. I know cars in the late 70s had them, I am not sure when they started using them. You can identify it by looking for a heat stove on the passenger side exhaust manifold that has a tube leading up to the air cleaner. If you have a THERMAC door that is malfunctioning it could cause poor idle or harsh starting conditions. The THERMAC door is in the air cleaner and channels outside air to the carb during normal operation and air off of the heat stove to the carb during start up. Just an idea.
