You may have missfire at 3th cylinder that related with fuel side of cylinder. Check fuel pressure and injectors. And if you had disconnect the battery may need remap or flash your ecu with proper tool.

SOURCE: new plugs an wires,coilpak what else could

This is the only possible ideas I can thing of :

Fuel injectors, related wiring, sensors and computer issues
Running out of gas, or poor fuel quality
Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine
Incorrect Fuel Pressure
EGR system concerns: leaking EGR valve or restricted ports
Base engine concerns: low compression, valve train problems and timing issues
Ignition module or related wiring issues
Ignition related sensor faults or wiring issues

I know you did these two things:
Faulty spark plugs
Faulty coil or related wiring

I have a misfire # 4 cylinder on a 97 Nisson Altima 2.4. Did complete tune up, has spark, good compression, swap #1 and #4 injector, problem stayed at #4, p0304. I read that intake could cause this but...

Did you check the coil pack to that cylinder? The best way I know how to check an individual cylinder getting fire is by using a induction timing light tester..start the engine then clamp the tester over the plug wire and point at a surface that will clearly show the flash of the light when the wire has power going to the plug..if you see an intermittent flash it is the coilpak...give it a try..a good luck..

After changing plugs wires and coilpak #3 plug has misfire

Would think you may have replaced the wires on
the wrong plug

Have to mark both ends of wires with a ball point,
as you remove them & make a drawing of distributor
cap, before your start

You should have all your reference material weeks in advance
of any auto work or repairs,can't guess or ask later

Check engine light on

When the check engine light flashes this is a class a misfire. If this is a 1999 you have a spark plug or a spark plug wire bad. Get a tune up done and replace plug wires.
