OK, recently (a month ago) I was getting full boost out of my SC, now I'm not getting anything. I initially freaked because aside from my girlfriend, my car is my baby... 97 GP GTP. I checked vacuum lines all seem solid, checked the coupler, solid, I check the valve lever, it appears as if it's not 'free'. The actual lever itself that's connected to the plunger sticks, the lever unless u take ur finger and press it down WILL not rest on the metal nipple or fully retreat to a vertical point, what should I do, I've looked on, in,throughout this forum, the best and cheapest answer is wd40.
