    Cylinders 2 and 5 are on the same coil pack. Obviously you have access to some sort of scan tool to know what cylinders are misfiring. Swap the 2 5 coil pack with one of the other ones but keep plug wires hooked up same way they are now (meaning ignore the numbers on the coil pack). If the misfires move to different cylinders corresponding with the coil pack u switched than replace the 2 5 coil. if the misfires stay on cylinders 2 5 replace the ignition module. Start there then report back.

    What he said ^ Start there and report back. Sounds like you have a bad coil or ICM.
