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. Zee

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
