yes stock intake, but I pulled it and resealed it after I got it.

I did an initial test yesterday plugging the pcv hose to the intake, I didn't hear it stutter like before. but my test got cut short due to the rain coming in.
will try again this weekend or maybe today if I get time.

but shout out to fastman efi if this works. he didn't have to tell me what it might be, but did and it probably cost him a sale because I was prepared to just chuck all of this and get a new system with support.
