My 2000 GMC Safari will misfire sometimes and when i stop at an intersection it will idle rough then runs ok What is the cause of this ?

p300, is a generic code for misfires. Could be any of the cylinders or all. When's the last time you had a tune up? Start with the cheap stuff, fuel filter, air filter, and clean the throttle body. If that doesn't clear it up, replace the plugs and wires.
