I assume you have already replaced the coil 'pack' so the first link above will demonstrate how to test the coil pack circuits .. If the circuits at the coil pack connector fail that test, for a small fee you can use the second link for more involved testing using a diagnostic flow chart and pin out schematic .. Don't know your skill level or tool box arsenal .. IF not equipped to complete the necessary testing, you may want to consider having a qualified 'mechanic' check this out for you before condemning any parts/components .. Good luck!
