Hi Guys
I’m having a problem with my ls1 turbo the bov, fpr and boost gauge is plumbed in the port on tb the blue hose in the photo. The idle is all over the place to the point it will stall. If I unplug the bov,fpr and boost gauge and leave the port open the idle is perfect. Any help would be appreciated
Thanks
Ashley

Sounds like it's SUPER rich for some reason. IAC problem, throttle closed too much, hanging injector(s), ruptured regulator diaphragm. Introducing so much air through the small port when you take the hose off is just helping lean it out. Could be wrong, but that's where I'd start.

If that is indeed a vacuum source then ok. If you are introducing more air into the engine (ie vacuum leak) and it starts running better it is definaltely rich. Disconnect the brske booster hose if you have 1 and see if it does the same thing
