Wait, everyone hold up a minute...

Over the last few days, a clear understanding of the vacuum system components has been bestowed upon me...

That check valve lads to the half of the vac system that controls the SAI function and the resonance flapper.

This means two things -

1 - you have a MASSIVE vac leak if that is not hooked up properly

2 - you resonance flapper is not functional

Both of these things will cause problems while running. Especially the vac leak - stomp on the gas, get a huge amount of unmetered air, run super lean, detonation...which is your problem right?

That is, unless I've totally missed something
