Thanks, I am familiar with the intake boot problem, I had that one when I
bought the car, and fixed it, thanks to this list!
Unfortunatley this is not the problem tho.

1)Try inspecting your boots in the intake tract, they are known to tear
and then when the motor rocks, the tear opens up and causes a massive
air leak.
2)Digifant is way cooler than CIS/Motronic. YMMV.
