This thread has been very informative. Thank you. The same stuttering, raggedy running has commenced again since replacing my coil pack 51 weeks ago. I am interested in the observations that the wires may have something to do with it. Should I replace the wires first ( 60k on original set ) before replacing the coil again? Reason I ask is I don't want the coil to hurt the new wires if that is possible. I did look at the wire ends where they insert into the coil pack and they are uniform in color. After rereading the post, I see that the discoloration was actually noticed inside the coil terminal. I might need to remove the coil pack in order to see down inside the connection tube. It's late and tomorrow will be a good day to check that. Also, do the autolite wires have to be purchased at a Ford dealer or can they be bought at a auto parts store? thanks
