2004 4.0L Cold start issues

[JCark01]

When it's below below freezing outside my explorer has trouble starting and initial rough idle. When I scan for trouble codes I get P0302 which is a misfire on cylinder 2 and a P0316 which is engine misfire detected on startup. Once it's been running for about 30 seconds to a minute the rough idle goes away and everything works fine. My mechanic compression tested each cylinder and it came back above 150 PSI for each cylinder. I checked the IAT and ECT sensors live data (with torque OBD-II app)and they seem to be working properly. Any ideas what would cause this? I already did new plugs, wires and a coil pack. Any help would be greatly appreciated! Let me know if you need for info.

Fuel injector leaking or sticking?

My explorer is doing the same exact thing! I have a p0306 and a p0316.
new dorman intake manifold, new motorcraft plugs, new cop boots.
I have moved the cops and fuel injectors around but the misfire stays in cylinder 6.
Compression for 1-4 is 190psi, 5-8 170psi. I hooked up a vacuum gauge to the brake booster vacuum line, upon cold start up gauge starts at 180inhg then immedietely drops to 140inhg for around 4-6 seconds then climbs back to 180inhg and steadily stays there as it should. this only happens during a cold start or after the engine being off for around 30 min. I could post a video of the vacuum gauge but I don't know how.
