I just got done doing a heads swap, I swear up and down (as many of us do) that I tightened this stud. The stud I am refering to is the one that is on the Drivers side head on the backside. It was lose damn near came off. What does it ground. Is it the knock sensor ground?

 

There was 2 on the back of my head. One is for the fuel pump (had to pump some gas out before) I dont know what the other is for yet.

 

I believe its the PCM ground, very important.

 

I had 3 ground wire connections to that spot.
