I have a pretty good idea what it is but I've been lazy lately and haven't looked. Figured I'd post here before I start looking to see what everyone else thinks. I get a miss everytime it rains. It started as 1 cylinder and now it's up to missing on 2 at times. I'm 99.9% sure I have a cracked coil. What do you think?

it could be a few things, but your on the right track, if they are companion cylinders that is most likely the case though

try putting some dilectric grease underneath the connections on the coils for the wires. I had an issue like that, could be water interfering with the connection. More than likely the rubber behind on the ICM connection is shot, or the coil itself is bad. Happened to me and I had a black mark on the outside of one of the ICM slots on the coil.

also one good way to see if theres a crack in one of the coils is to just pop the hood while its running when its dark so there is no light and believe it or not sometimes you can see flashes or small jolts of current jumping to ground... then ya know . Other times of course your not always that lucky lol

Missing when it's wet out is most likely a bad coilpack(like you already mentioned). You can isolate which one is bad sometimes by misting each coilpack at a time w/ an old spray bottle filled with water.

Pretty sure I figured out the problem. If I'm right I'll update with a pic tomorrow.

Ended up being a bad coil as I suspected. BUT, there are no cracks in it and the seal between it and the Ig. module was good. Take a look at the pic. I have no clue what happened to it. Both terminals were like that. http://img.photobucket.com/albums/v293/redturbo90/89%20CS/11-27-062.jpg?t=1164666136Also, if you're working on your coils/ig. module and set it on the front of the car, be careful not to knock it back in towards the motor. You'll end up with one of these. http://img.photobucket.com/albums/v293/redturbo90/89%20CS/11-27-064.jpg?t=1164666319Couldn't find the proper size socket so I pulled the oil filter so I could use a crescent wrench. So I ended up changing the oil today also. It was at around 5,000 miles anyway. (I use Mobile Clean 5000 BTW.) What should've been a free repair ended up costing me around $40.  |

5.5mm is the proper size to hold the coil packs/icm to the bracket. the bracket to block is 13mm but i've encountered rusty ones that no sockets fit right.

I had the icm/coils off. That's how the oil switch got broke. The socket was for the oil switch. And I know what size it is. Just didn't have one that I could find.  |
