Check the cap and rotor. It could be loose or bad.
New parts don't always mean good parts. They are used as soon as you install them. New parts have failures too.
The ignition coil is usually good or dead, while a misfire is possible and there can be some pretty severe leakage, a bad misfire at idle is not usually related.
Using insulated pliers remove each plug wire and see if you find one that doesn't change the miss. That would be the plug or wire to suspect. swap the wire and see if the problem moves. If it doesn't, pull the plug and check it. If it looks ok, swap it and see if the problem moves.
Check for vacuum leaks. Spray some carb cleaner around the suspect areas on the intake. Look for a loose or stray vacuum line.
Check the fuel pressure. Run the fuel system checks to rule out injectors, check valve, regulator and pump.
When was the last new fuel filter installed?
Have you been using some injector cleaner routinely?
Did you get some bad fuel?
Narrow down the suspects and then start interrogation
