The code 300 is a Random/Multiple Cylinder Misfire....a 302 is Cylinder # 2 misfire detected. ..and the same for 304 and 306..being 304 is cylinder 4 misfire and 306 is cylinder 6 misfire...All these at the same time normally is a faulty coil pack..,and or faulty coils...spark plugs.,plug wires.....It should be running horribly or barely ....However it could be internal losing compression.....It could just need a good tune up.....Disconnect battery before changing coils,wires..,or plugs in order to clear the fault codes.....

This is almost for sure the fuel relay. I do not know where it is on your car but I would look for it to be by one of the back wheels where road junk can get to it and corrode it. Once found not very expensive and very easy to replace.

2003 Kia sorento starts and then won't start

There is a black rubber button reset switch right next to the air box, press it sounds like the problem i had its a fuel pump reset (just in case of a wreck it kills the car) but there is a tiny ball in there and if it is rattled a little too much it will fall and you need to press the black looking button to reset it....took me like 4 months to figure it out
