Default Really need some help

I have been fighting this issue for awhile. Last year i put in new plugs, cap rotor wires. And it stopped missing about a week after that. Now for the p[ast 2 or 3 weeks it has gone back to missing again. I hooked it up to a scanner and i have a cylinder 5 miss fire. I pulled the plug and it looks good. I tried taking out the injector but they were stuck and i didnt wanna break them. dose anyone have an idea on whats goning on? I though maybe coil, but its only a number 5 miss. wire maybe? injector? valve? any help would be great.


thanks

Could be caused by best soak at the injectors. Try making up a heat shield or wrapping them in heat wrap

It will. Do it randomly. Some days while cold some days while hot. Start in the moring and then go away or start in the after noon and then stop. Some days wont do it at all. Im at a lost.
