Saturn 1994/ Make???

I have recently purchased a Saturn(Used)and I don't know the make of the
car. But that is not it When I start it up(When set down for more than
five hours) after putting it in First gear it wouldo move about half a
foot and it would start getting back as if there was no gas going in it
then after i pat the gas a couple of times the engine alses up and the car
takes off.But thats the only time that it dose that then when I park the
car for some odd hours it will do the same thing. I was wondering if there
is any one that could give me some kind of explantion for what is going on
with my saturn?
