I noticed that you didn' t mention the plugs. I'll assume that if you did wires and coils that plugs are also new, so I would say that you need to check the injector on that cylinder

SOURCE: when the car is idling
if vehicle has been standing for a long while it could be the fuel has gone stale but i wouldnt like to say as it could be a multitude of reasons ranging from stale fuel to a mass air flow sensor ,so i would advise that ask a local mechanic to have a look for you

use a digital volt meter,put it on the ohm scale check number 2 fuel injector should be 11 to 16 ohms if not reads zero fuel injector faulty.if numbe 2 fuel injector okay.use noid light hook it to fuel injector electrical connector with fuel injector disconnected and see if pcm is firing the fuel injector noid light should blink when cranking the engine.if light steady pcm not firing 2 fuel injector,if noid light dont light up.there is a open in the wiring connector 2 fuel injector 2. if fuel injector okay,check spark plug, carbon foul you have a bad ignition coil or wire if you see oil on spark plug you have worn piston ring or leaking valve guides allowing oil to foul out spark plug.do a compression test check compression to see condition of the cylinder.
