How do you know it’s specifically cylinders 2 and 4 that are misfiring? Has the check engine light come on, and the codes were read? Those would help us a great deal, but one guess at this point is perhaps a faulty ignition coil, assuming that both cylinders are tied to the same coil.
The overheating is very hard to diagnose without more information about when it happens. Does it happen when idling, in stop-and-go traffic, at highway speeds, all of the above? Do you hear the fan coming on? Does it only overheat when the A/C is running? When does it start to overheat, when does it cool back down?
Use an ignition coil from the salvage yard, for the misfire.
Make sure the radiator is full.
Swap the fan relay (in the relay box under the hood) with one of the other relays.
… and how do you know it is overheating?
