Smile Misfire after changing plugs? Check this fix!

Hey everyone.
I changed out my plugs on my 2002 WRX wagon yesterday for the first time (new car to me) and man... What a PITA compared to my b-series swapped civic!

Anyways, all was good and the stock temp NGK iridiums I put in made a noticeable difference vs. the old & used up one step hotter NGK-Rs (no surprise). The car was really doing much better until about 30 seconds from work today! Then all of the sudden I lost power, and the CEL started flashing... definitely felt like a misfire. I tried to pull the code with my canobd2.com 3100 C but it couldn't read it (I fixed that too by upgrading the software WOOHOO!) so I was on my own.
I limped the car home at lunch and took the Kawi back in. When I got home after work I went to work pulling all the plugs (waaaaay faster this time!) and when I got to the left hand rear plug I found the problem!
It seems that the tab that clips the coil on plug assembly to the harness snapped off and it had just fallen off!
I called the local dealer... $160 CAD for the part. Then I went to Home Depot - $2.91 for Krazy Glue Gel... GUess which one I picked

So I glued the plug on with a generous amount of Krazy glue and left it for about 5 min- it's on there for good now and the car is running solidly again!

Soooooo long story short: If you just changed your plugs and now you've got a misfire be sure to check all the coil->harness connectors to make sure they're really "clicked" in and secure and not simply "pressed in" with a broken clip!

Cheers!

I don`t like to glue anything because if I would like to move something around, I won't be able to!

look at the bright side: at least it wasn't duct-taped!

but I'll have a hard time justifying spending $160 on a little plastic pos too

Keep an eye out if it reoccurs, I've found that crazy glue (cyanoacralate [sp]) to make plastic brittle (kinda like overcooking welds where the weld is ok, but the metal around is fatigued). Maybe a 2 part epoxy might be a good option too.
