Help Help Is it a vacum leak

[Bobbys14]

Rite story is car not running 100% on idle but fine when rev'd up, the boost gauge is reading .02 vacum should be .08 and the waste is open slightly can hear it out the screamer pipe, can also hear like a leak around the throttle body but can't sourse it any way i can check for a leak without the engine running? Is this even a leak or another problem??

Thanks in advance

Would a leaking boost pipe only affect the idle or through out the rpm??

It would affect the idle big time but if its not bad the bar will still rev up cause the airs moving trough it so fast but you'l have no boost still........! Thats what it sounds like to me......... Its the fisrt thing ya look for when that shit starts happening..........!

Should the waste be open on idle??
