Boost control solenoid

[m_dogg]

I was running new vacuum lines and probably never paid much attention to it. So this vent (or whatever the correct term is) is sucking air at idle. I don't believe it should be plugged but should it act like that?

I can't fucking remember how this valve works, but if that solenoid is actively pulling air at idle I'm thinking both the valve and the solenoid need to be replaced. And the PCM.

solenoid on/PWM modulated ontime it feeds lim vac to bbv actuator to open bbv.
closed the solenoid is supposed to plug the vac source and connect the bbv line to atmosphere(the port withthe metal bracketr that used to hold a foam block to keep debris from getting sucked into it....to reduce the vacum.

you shouldnt have vac leak at that bugger something probably got sucked in and its stuick midway

Replaced with new, don't feel or hear any hissing. If I connect/dissconnect either plug with hose from bbv it won't change MAP values at idle, sit at ~ -20 inHg so I guess old one sucked some bad shit in and is not closing like doctor said above.

When they were new, they had a foam filter over the nipple. Supposed to be like that.

the diaphragm on yours probably failed, pretty common

I think I have a few of these laying around if anybody wanted them
