intermittent misfire

Whatsup fellas...i have a 95 gle, but im posting here to try to get some feedback.

Long story short. Got a misfire code for cylinder 4. checked spark plugs...fine. checked injector. dead. So the other day i replaced it.

still misfiring. 2 hours later started it up again...no misfire.

then yesterday, saturday, misfired all day.

today, drove it at liek 5pm, misfired. three hours later, drove it again...no misfire.

what the hell is up? does anyone have any idea what could cause an intermittent misfire like that?

Possibilities for an intermittent misfire like that:
- plug(s):how did u check your plug? Did u swap plugs 4&5 to diagnose?
- coilpack(S): Did u swap coilpacks 4&5 to diagnose?
- ECU drives the coilpacks (not likely)

btw. hell is down, deep below...

i chekecked the injector by checking the resistance. none.

so i replaced it.
