Default Misfire question again

So i went to grab a bite to eat and started the car as usual. I didnt wait to warm up the car cause its like 80+ degrees here in the PACNW. Got to the traffic light and it bogged out, like it needed gas, like how a bad TPS sensor would act. Check engine didnt light up at all. Went to get some food, started it and idled fine. put it in first and it started acting up again, this time with a solid CEL on. Got to work, parked it and did a code check, It read misfire Cyl-4. The other code did not show due to the ability of the code reader not having the manufacture "HONDA" listed. So i ran it under Mitsu. and it read "Random misfire". Is there a reason why its on Cyl-4 only. I searched and found some misfires buy nothing on just Cyl-4. Is there a quick fix with some common hand tools till i get home?? I just dont have too much time since im "on the clock" working on my car .

Common issues that cause misfire are:

1) Plugs need replacing
2) Bad coil pack
3) Bad injector

Move the coil to another cylinder to see if the missfire moves. Same can be done with the injectors and plugs.

cyl-4 coil on the bottom has sorta a rust/oil issue. no leaks tho. It could be because its closer to the oil spout?? but i switch plugs from 4-1 and no misfire or CEL yet. i didnt do the coils yet, i just wanted to see if its the plugs. But instead it stalled for the very first time since i've got it a year ago. I'll be driving home tonight('bout 20mi) and i'll see what happens. Im taking the tools with me.
