i already replaced coil pack on #2 last december. fault still persists that cyl 2 has misfire. all spark plugs are changed....

just read this on another forum.. "Well, when the lifters go bad in these motors, the lifter collapses and doesn't lift the valve all the way; meaning the cylinder isn't getting a complete air/fuel charge. The lifters scour the lifter bore in the cam ledge, creating escape passageways for the oil to travel instead of pumping up the lifter."
