Alright guys, I just wanted to thank everyone for their help! The spark plug was indeed the problem, and after re-seating it my engine purrs like a cat.

It's kinda funny because I used the justanswer.com (ask a mechanic) for 15$ freaking dollars. And after 2 long days I finally got a response, but according to him the problem was a blown exhaust gasket. I'm so glad I didn't just take his word for it, and order those gaskets.

Anyway, thanks again guys, you saved me from having to haul this thing over to the dealer and pay a lot of unnecessary cash. Thanks for all of your responses!

Doubt it's an exhaust leak.... the headers have individual round gaskets that stick into a cutout in the cyl head at each exhaust port. Virtually impossible for them to come out or blow out anywhere they way they're stuffed in there. Exhaust leak wouldn't cause a huge power loss either. Some yes, but not a huge amount especially if it's only on one cylinder

To me it sounds like you blew a spark plug out of the head. Pull the coils off and see what you find
