In the process of troubleshooting my ignition problem I have either replaced or swapped out all things involved with the ignition. I replaced the trailing coil pack and the coil harness, and in the process I inspected my leading coil pack and it appeared okay. My question is: although appearing to be okay should I replace the leading coil pack? After replacing the trailing and the harness the only thing that seemed to improve was the idle. Which is great but did not solve my problem, as far as I know the leading coil pack could be the original and the vehicle is a 93. So if you have any input it would be greatly appreciated. thanks Jamie
