car doesnt start right

i hAve a 91 dodge spirit , and when i start it , it starts off soundin like theres very little battery power to it then it starts. after it starts it runs rough fer a minute or two , whats wrong???

you probably have a weak battery. Weak batteries can cause not only slow start-ups but also driveability issues. It never hurts to check your charging system in the process, make sure it's putting out between 13 to 15 volts.
