You are right, I should have included engine size in my query. I meant to do so, but forgot. My engine is the I-Force 4.7l v8 DOHC. Thanks ever so much for your prompt reply. Upon doing some further research, it would seem that the COP is a common fault with these engines. I will do as you suggest and replace the coil. Also, since it has been close to 40,000 miles since my last plug change, I will replace all spark plugs.
Thanks again for your response. I will post results of the above corrections.
