It seems to be a common issue with that engine. He did break one spark plug during his replacement, but doing the work himself saved him hundreds of dollars. I may put my car on the ramps this weekend to see where everything is under and over the engine so that I will have an idea of where the spark plugs and oil filter are located. If nothing else, I will at least become more familiar with the car.
People also use a product called SeaFoam to rid of carbon build up and other gunk and built up stuff in the engine.

Seafoam would be a good option IMO.
