I havent changed my coils because everybody seems to say that the coils eithe rare working or they are not, they dont degrade in power prior to them dying. I dont have any missfires or anything so I think my coils are ok. unless my understanding of changing the coils is incorrect which is entirely possible. I was leaning towards the plugs and the walnut blasting as well, but can the gunked up intake cause it to feel that slow, but then completly normal after 4,500rpm, is that a common symptom?
