So as I and others had suspected... incorrectly torqued spark plugs were allowing pressure to escape and force the coilpack off of the plug and to pop up.

Problem:

Raised coil packs were causing some stuttering under heavy boost at mid RPM's and a somewhat rough idle. As you might imagine, performance was definitely impacted as well.

Diagnoses and Solution Steps (Use at your own risk):

Diagnoses:

1st -- Remove Engine Cover and Inspect coil packs

2nd -- If any coil packs are raised up push them back down and drive normally for a few miles.

3rd -- Inspect coil packs again if any are raised, try swaping the problematic coil pack with a coilpack that is still firmly in place and repeat the second step.

4th -- If after the swap the coil packs are raised (this time same spot but different coil pack) you may have the same problem as I so proceed to solution.

Solution (again use at your own risk):

1st -- remove suspect coil pack

2nd -- use a torque wrench to tighten the spark plug in that cylinder to 22 ft/lbs

3rd -- put coil pack back on and repeat for the remaining cylinders to make sure you dont have any other loose plugs (I did even though they weren't causing the other coil packs to be raised)

Hope this helps anyone with the same problem... probably not the best write up so if anyone wants to see this spelled out a bit more clearly let me know.

lol.. no offense.. but is there any risk in what you are saying ?

I had the same issue

Might want to do a compression test by now, might have mess up some piston rings. I don't think you can just switch sparkplugs around not a good idea.

The coilpacks have a wiring harness right at the coilpack. Swapping coils between cylinders is no different than swapping plugs between cylinders.

it's called Musical Coilpacks, and I've played it more times than I'd like.

Obviously if you have a clue there shouldnt be any issues, but I dont want someone messing up there coilpack or over torquing there spark plugs and messing up there head, just to point the finger at me

Please don't offer horrible, misguided, incrrect advice like that *evar* again.

How, pray tell, can you mess up the firing order by mooving coilpacks and plugs?

Piston rings messed up?

You scare me. Please tell me you do not do *any* work on your own car.

BSK auf Arbeit

it seems like many people dont understand that

Agreed
