ok I'm checking my plugs and peeking around because of the 0130 code

can someone confirm something ? On top of manifold you have 4 bolts holding it down kinda of in the middle
now forwards back of manifold at the base I see a Empty hole like a bolt is meant to be there ??
I don't get vacuum there but it's open

can someone confirm what's suppose to be there ?

It’s got 4 long 10mm bolts & two short 10mm head bolts holding into place. Front one is dead center on the front lip of the intake & the rear one is dead center on the back just above and in front of the coil pack mounting area.

I'm missing a short 10 mm bolt then.
If water was to get in there would it make its way in ??? There was no vaccun leak
