Help! What's this bolt hole near Plug #6?
 

Am I missing something? This is a bolt hole just below plug #6 (driver side plug / closes to firewall).

Should nothing be bolted to that?

Its used for coil wire harness bracket mount which may have been removed.

Ok, I may have installed the coil upside down. The letter f on the coil should be facing right side up like the rest of the coils right?

#6 coil pack is reversed from the other 5 coil packs. Orientation of the "F" on coil pack is irrelevant, whats important is its seated all the way on plug and tightened.

#4/#6 are common problem reversing harness plugs because of orientation.

Yeah, I just saw some pics and the #6 is upside down.

The missing bolt is weird since I never touch it before until today. Unless the dealership removed it.

I forgot to plug in the damn intake harness and turned on the car. Now the check engine light is on.

So it's either that or the #6 plug isn't plugged in all the way.
