Cleaning coil packs

HAs anybody ever done it? I think I found out the reason my engine is running like crap: one of the connectors between the coil pack and the plug, inside the rubber houseing, was sitting sideways, instead of up and down, and voila, put that baby back right, and now it runs decent. Im going to test it out again and see if it still happens (the misfiring), and then update this thread.

But, can somebody who has seen or done this operation post some pictures or a how-to guide? Or point me in the direction of a site that shows you how? I saw a site for cleaning RB coil packs, and they look the same, but I want to be more sure than that site.
The engine is a ca16de, but uses the same packs as your ca18 engines.

Thanks alot,
Jesse.
