I don't know if it will help, but I also have the magnacore wires and have noticed that sometimes if you put your hood up in the dark (garage or at night away from lights) you can see a spark jump out of the wires! WTF?! be careful about adjusting them with the car one b/c that spark has a little bite to it. But yea, check that out b/c sometimes if can make the car feel like it is misfireing, or cutting out while you are driving. Plus try some of that elctro-grease(or something like that) from any autopart store. Little package of it cost like 70 cents. But good luck, don't forget to post what happens when you put the stock wires back on.

ok I have putted stock back and same thing, I don't get miss fire while i am driving, ONLY at very first when my engine is in idle. I have RRM header and my engine light is on. I just went to the autozone and got the light checked and it reads something like high voltage, Too much air flow. So does anybody have this problem with RRM header??
you sure the gap is right? 0.44 sounds big. Shouldn't is be like 0.42-0.40 
That could be causing a weak spark and only after a few minutes of stumbling is enough heat stored in the engine to help ignite the fuel with these weaker sparks...... just a thought.

o2 sensor?....wouldnt causy your car to run lean, or misfire unless but am not sure, its th e 1st o2 sensor, the second one wont pu it in a closed loop....if its fuel, then drive around till its gone fill and start aLl over again
O2 sensor hasn't a damn thing to do with spark. you're basically telling us you don't know jack about engines, tuning, etc. and then telling us we're wrong without checking. Nice.
Go get the dielectric grease from the parts store and lubricate the ends of the plugs, the connections between the wires and packs and try again. Double check that gap, too.
And blinker fluid might help.

i don't know lot about engine but i do know how it runs and work. what i said was because of miss reading of my o2 sensor i might not be getting proper fuel.. and i know it not the spark plug since i only get the misfire at the beganing, just for first 2 min of my engine start..
