Well, I was driving back from laundrymat and car just started to idle and run very bad. Pulled over and looked at the car and everything looks right, but my vaccum line (on boost gauge) was reading kind of funny @ -13 to -10 usually its always on -20 idling. Then i check all vaccum line but found no leaks. So i called up a good buddy of mine who knows what he's doing, and said it could be the stock bbdet blow off valve that's shot. Because we took the BOV off (off of the intercooler pipe) and car idle and rev fine as normal but with BOV on was crappy. Any suggestion on what's wrong? Is it the BOV? Any help would be appreciated.....

Thanks,

Is the BOV recirculated or open to the atmosphere? If atmosphere, then it is definitely the problem, if it is recirculated, then look elsewhere.

No, the air is recirculated back into the intake to turbo. But don't know where else to look.

check the hose that goes to the bottom of the throttle body, it gave me trouble once before.
