I have a 2004 B2300 that is experiencing vacuum loss on acceleration. Symptoms include the blower direction changing from dash vents to defrost when I accelerate indicating no vacuum pressure and a high/rough idle. The engine idles anywhere from 900-1100rpm but usually sits just below 1000rpm.
I have checked the ball shaped vacuum reservoir that is bolted to the passenger frame rail beneath the air box and found that it holds vacuum pressure using a vacuum gauge. From what I can tell, both of the lines that run to the resovoir, one from the intake manifold and the other into the firewall, are intact. I'm not sure what else or where else to check for this. If someone could steer me in the right direction that would be awesome.
If anyone has access to an accurate vacuum system diagram for the 2.3L DOHC motor that would be extremely helpful. I can't seem to find a decent one.
