A few months ago I was driving and suddenly (without prior warning) I hear a very loud tapping noise from the engine (similar to a belt flopping around). I check it out and it turns out to be a loose spark plug and the coil pack was jumping out and hitting against the engine cover. I did the 80k mile service, replaced all of the spark plugs and cleaned the coil packs. Problem solved, so i thought.

A couple of days ago I was getting a stutter in the 2-3.5k rpm range. I did a search and everything seemed to point to the n75 valve or the maf and possibly the coil packs. So I went to my car and checked out the obvious and easy. Two coil packs were popped out and one was beginning to.

Is there anything I can do to prevent this from happening in the future? Is this the common problem with these and should I upgrade them to the revised versions?

make sure its the right one, tighten in there properly etc.

and lets gases escape through the threads which will make the pack pop up like a bullet out of a chamber
