sounds like you're coil pack took a dump. How many miles? Mine died at about 104K

What brand plugs and wires?
These engines can be very picky, especially about store brand wires and certain brand plugs.
#2 and #3 are on the same half of the coil. It's a strong possiblity if the wires and plugs are not the problem.

Would be part of it. If that Coil is origional best guess says thats you're problem. I replaced mine with an Accell one I got used with very low miles for $20. Brand new they go for about $80. Autozone has a wells one for $43. Before you run out and buy a new coil pack though, what kind of wires and plugs did you use?

yeah, check into you're coil pack then. I would give you my other one, but I replaced it with the accell one because it was defective. I would get a random misfire pas 4K rpm's. My origional coil pack died and quit firing one of the cylinders completely. I replaced it with a ford one which after a month started giving me random misfires on more humid days. Then I replaced it with the accell one... That one made me really happy
