Hey. I have an 05 Subaru legacy 2.5 gt.mods include fp black Turbo. Fmic. Borla headers with perrin up pipe and down pipe. 850 CC dw injectors. Grimspeed air fuel seperator and light weight crankshaft pulley. Recently installed a brembo brakes and Cobb SF intake tial q bov and Cobb ap. After I.changed the bov out the other day there appears to be a vacuum leak everytime I slow down the rpms drop down to like 200 sometimes just dies. And sometimes if I let it sit and idle it goes.crazy too. Any ideas on.what could be causing the misfire codes or p1491 code or p0030 codes?
