Check Engine Light

I just replaced my spark plugs, started the vehicle and it was running rough and the check engine light came on. I shut off the vehicle and inspected my work and found that one of the connections came lose from the plug pack. I reconnected it, started the vehicle and its runs great now but the check engine light is still on. Does anyone know how to reset the check engine light or will it go away in time?
