you shouldn't have a distributor on a 2000 accent... is this a USA car? 1 and 4 are companion cylinders so most likely it is either one of the spark plug wires are bad causing an incomplete circuit or the coil for those cylinders is bad. test the wires first and if they are in spec, test the coil.

Did you check the gap on the spark plugs and clean out the leads?
