=> There are 2 "pipes" that are part of the 2 piece housing
=> around the main fan.

Known as 'heat elbows' and 'fan shroud.'

=> The right hand plug is gone from the housing.

These normally go to the heat exchangers and air ordinarily flows through
them. Yes, having one wide open gives you less cooling air, but not as much
less as you might think.

=> Is it possible that I have a valve sticking or burned
=> that is causing this problem?

A burned valve would cause a consistent loss of power -- in essence you lose
compression on that cylinder. A sticking valve would produce the same result
intermittently, and could push fuel mixture into the exhaust. But this
condition won't likely come on suddenly.
