Answers :

The secondary air injection comes from an electric air pump (replaces the old eng. driven smog pump), it seldom runs, but when the car is 1st started you should hear if for about one minute, kinda sounds like a muffled hair dryer. The most common issue is the hoses get knocked off, 2nd is the electric motor failing.
