My 2008 acura tl type S which i had for since 60k miles and now at 75k. The other day i noticed the car making a pounding noise coming from the exhaust and soon to have a check engine light P0305. I ran the code and it said it was a misfire in cylinder #5 so when i tried to take out the coil pack it is stuck and unable to move. I then broke off the top of the coil and now there is 3/4 of the coil still stuck in there. How would i get the rest of the coil out? Do you think i would have to replace the head?

Thanks

 

Here is a picture of how cylinder #5 looks

 

Sorry to say, you're not the first. Plenty of work/$$$ ahead.

Spark plug loosened and the heat destroyed the coil pack.
They are just a few threads, so plenty of reading available.

 

What are the next steps? How do i get whats remaining of the coil pack out?

 

Silly question; butt have you tried pliers?

the coil pack tube itself pulls right out of the spark plug tube.
if there is enough of a lip, maybe you could pull it straight out with pliers.

 

I would recommend a pick set like this.

 

it'll be super hard, as it looks like its melted.

the picks are another good idea!

 

Heck, he might get lucky and just be able to screw the coil shaft and spark plug out in one piece.....

 

^good idea, i bet the spark plug is loose from the OP's description of hearing a pounding noise.

 

I had the end of the coil pack get stuck on a spark plug and OMG it was a pain to get out. Good luck!
