Yeah it happens when your spark plugs are gapped too close: from wiki
The gap adjustment can be fairly critical, and if it is maladjusted the engine may run badly, or not at all. A narrow gap may give too small and weak a spark to effectively ignite the fuel-air mixture, while a gap that is too wide might prevent a spark from firing at all. Either way, a spark which only intermittently fails to ignite the fuel-air mixture may not be noticeable directly, but will show up as a reduction in the engine's power and fuel efficiency. The main issues with spark plug gaps are:
· narrow-gap risk: spark might be too weak/small to ignite fuel;
· narrow-gap benefit: plug always fires on each cycle;
· wide-gap risk: plug might not fire, or miss at high speeds;
· wide-gap benefit: spark is strong for a clean burn.
A properly gapped plug will be wide enough to burn hot, but not so wide that it skips or misses at high speeds, causing that cylinder to drag, or the engine to begin to rattle.
I have mine gapped at 0.6 because my coilpacks are shit and i need new ones, but it fixes my hi-rpm misses, so until i save up for some splitfires i hav to put up with the missing at idle,
So yeah check the gap on your spark plugs, ideally should be 0.8
