1 and 2 are the Air injection , it lets air into the exhaust system to heat up the catalytic converter quickly . It is only for emission purposes , it won't affect the running of the engine .

Yes , a lot of cars had Air pumps to get through new emission regulations around 1996 . They only lasted a couple of years before ECU software was tweeked to do a similar job ,. Citroen kept the Air pump for quite a time though!
