Normally Oil on a Sparkplug indicates a blown piston ring.

which is not a good thing...
Or when you changed your oil, you poured it into the wrong hole

just called my mechanic he said it might be a fuel injector.

Is it oil or gas?

It was oil. But after i replaced the injector the car runs fine now. It doesnt miss anymore. Thanx guys.

I really dont see how a faulty injector would cause Oil to appear on the spark plugs. It would explain the missing for that cylinder, however oil on the sparkplugs is almost ALWAYS a blown piston ring. It might be 2 non related problems. I would still have a compression check done on your engine.
