The secondary air problem is most likely a bad vac hose...specifically the one that goes to the fuel pressure regulator. If you have vac hoses which are cloth, try replacing them with either rubber or better yet silicone hoses (3.5 mm inner diameter). If you open your hood and look on the black plastic fan housing at the front of the engine bay (where the hood latch is located), you will see a vac hose diagram. Good luck.
Not sure about the evap problem.
