ok heres what i have had happen to me feel free to post your missfire problems and how you fixed it
first my car had a small miss to start when i got it ..
gradualy the miss got bad enuf to the point the s/c shut off, then made it seriusly miss
so we cleaned the maf sensor worked wonders
untill i went into town ... the correct readings made the coilpack give out X.d
so after 115$ from nappawe fixed the majore :P missfire
now it was starting to get bad agen so i orderd a plug wire that goes under the coil pack (wondered why they sold them seprate ? get one and check the length)
replaced the wire from the bad coil pack now guess what..... absolutly no missfire nowfolows thru like a boss lol
there was a 1/4 in diffrence in length of the wire
anywho this is how i fixed my missfire still gotta put my bosh plugs in lol
feel free to say how you fixed your miss itl help others looking
