    Random or specific cylinder? Did you replace the boots as well. Check the spark plug again for cracks. Could be a bad injector...

    Is it only one cylinder? The code returned to the same cyl. that was misfire before?
    We need to know a bit more about the history on this.
    Hal has the right questions about the connector boots and the cracked insulation.

    it could also be a lifter or cam follower which will cause the first compression stroke to show compression but after that you will not have compression causing the miss i have seen this several times personally
