Im guessing completely here, but is there a chance the fuel pressure regulator is broken and therefore blocking off the hole 100% of the time? I dont know if I have vacuum on my 02, cant check it either b/c its 300+mi from me.

And Josh, I dont even know if you have the connection, it was late 03/04 IIRC that GM stopped putting a hose btw the regulator and the resonator.

Is this causing you any problems Steve, low idle, loss of power, loss of mileage?
