Hard to keep track here.....too many similar problems right now. A single-cylinder misfire won't be caused by a coil. Even the ICM is a long shot, especially if it'* the same cylinder each time.

Look into swapping plug wires between that cylinder and the one closest. Both at the coil terminals and plugs (to maintain firing order properly), or simply plug in a spare plug to that cylinder and see if it is actually firing (while holding the plug against something metal).

I still suspect either a plug wire (use an ohmmeter to check the resistance) or a bad valve fouling a plug prematurely.

i tried unpluging the wire and putting it close to something metal NO SPARK, i changed the wires and plugs, NO SPARK, changed the coil, guess what, NO SPARK......im gettin fed up, and my wallet cannot take the punishment, its beggin on its deathbed........i have some good news though, since i changed the water pump the ac is working wonderfuly, no if only i could get the damn car to work properly......too much to ask for i guess......

ive always had bad luck with cars, always.......imma buy me a bike, one of the schwinn sting ray bikes......
