Zeevert was right about all but one thing. Cylinder two is the rear middle cylinder on a V6 or the second one from the passenger side on a 4 cylinder.

po303 is cylinder 3 misfire, po304 is cylinder 4 misfire, po305 is 5 cylinder misfire. this means it could be bad plugs, wires. or coils that are bad. change plugs and see how it is running.

PO300 and P1399 are random cylinder misfire detected.
PO301 cylinder 1 misfire
PO302 cylinder 2 misfire
PO304 cylinder 4 misfire
PO306 cylinder 6 misfire
I would say that you have damage to the ignition wiring harness or you ECM is failing.

02 hyundai accent engine quit running won t start codes come up po300 po301 po302 not familiar with 4 cylnders when turning over sounds like no compression

codes p 0300 is random misfires and codes p0301,2,3,4,5,6,7,8 are the cylinders that are misfiring
so un you statement the problem cylinders are 1 and 2
misfires are normally problem injectors and low fuel pressures so have the fuel pressure checked to make sure that the pump is running correctly, the pressure regulator is operating correctly ans the EVAP system is venting the tank correctly
use a couple of injector cleaner in the tank to clean the injectors

2003 freeland code p1319 , misfire code po301,po302,po303,po304, misfire at idel, high speed drive fine,

OBDII those codes generally mean misfire.

P0300 multiple missfire
P0301 missfire cyl 1
P0302 missifre cyl 2
ect.

Ensure you have the proper spark plugs. Check the coil boots/wires, look for burn marks. Anything beyond that you may have to take it back to the shop.
You are misfiring on all 4 cylinders and it is not spark plugs. Those misfires if not addressed can cause serious engine and/or cat converter damage. There are lots of things that could be causing it and most of them need to be checked out at a shop - unless you want to invest several thousand dollars in the appropriate equipment and training.
