Got some problem

[bobpogoman]

i just took off my accordian hose and i found a lot of dirt in there...i checked all other hoses...(ic pipes and etc) theres nothing on them...the oil seems to come from 1 of the 3 hoses (theres the bov and 2 other hoses) on the accordian hose...need some help im also getting turbo or boost problem code and knock sensor problem code....the car is kinda misfiring when i got the pedal on the floor....but always the same time between each misfire like MISS.....MISS.....MISS.....MISS etc... the fuel pressure regulator was plugged at the wrong place so i replaced it but 1 of my vaccum seems to be blocked i repaired it and now its better but i still get the misfire problem...
