how important is a coil

[snipez]

sure i know it sounds like a dumb question, but,

if one coil is giving off a bad spark (6 in total), what will that affect?

[C_Sephiroth]

1 Coil Will Generaly affect 2 sparks, if it goes to long it will take out the Ingition module, and possibly the other coils

[snipez]

how hard is it to replace the coil? or should it be taken to the shop?

the coil packs (3 of them) are held onto the "cradle" by 2 bolts (If I remember correctly the bolt is 5.5 mm) very simple fix.
