Porscher,
Remove the CIS rubber boot between TB and AFM unit. And do a pressure test. You just need a continous flow of pressurized air (no more than 5 psi.) to pressurize the air box and the intake manifolds. Plug the two (2) vacuum hoses that go to the CIS boot (Pope), POV, and throttle body. A latex glove over the TB is one option. And keep us posted.
