Well I didn't think I'd be having to ask this but for sanity check the bypass valve should hold a vacuum correct... I've been thinking something was up lately with just minor drivability issues and I finally got around to checking for vacuum leaks. Sprayed carb clean at anything that I could think would leak and nothing. For Shitsandgigs I figured let's check the valve and it doesn't even try to hold a vacuum. It's the updated valve that has been in the car for the last year and a half/20k and has been flawless until now. Guess I really should've installed that relocation kit I got from BT a while back
