While getting my coolant issue all fixed up, turns out it was a hose coming loose, I was looking around under the hood and noticed I am missing a part. LEt me describe where it is.

Looking at the engine head on, on the right side where the oil refill cap is located. Now, just behind the (going toward the cabin) there is a "hole" where it looks like some type of cap or plug would go.

Does anyone have any guesses as to what may go there? Right now there is just this hole sitting there, while I am no expert on engines I am sure there should be something plugging this thing.

I am also getting a lot of hesitation or "missing" when I accelerate. When I get up to freeway speed (65+) it gets pretty bad. I am thinking it is just wires, plugs, etc... Do you think the hole I described earlier could have something to do with this?

I have checked all fluids and they are full. There are no leaks or anything of that sort.
