Emission Test Failure

IT PASSED!!!

It was on the gas analyzer, failing, inspector's playing with things, accidently knocks the vacuum line off the FPR, and results change to pass.

Best answer is: brand new fuel pump cannot keep up with engine...Before I ever got it tested I installed a new fuel pump when my old one died... I've now been through everything on this car related to fuel (and I always saw 30-35 psi idling, revved up, but I guess I never watched it under load). Must be a volume problem?

Thanks for everyone's input. It helps not being in this alone.
