I am getting a misfire on cylinder 6, I am planning on using a coil pack from my other engine to see if that fixes the issue. I pulled it out and it has some white stuff on the plastic, it is clean, the electrode looks good, any reason not to use it?

 

@silvergl Can you post a well lit, clear photo of the inside of the boot? Does it look good? Does the plastic feel solid? If you can replace it with a new part, that is always best. If you re-use it as a test, and are willing to replace it later if necessary, then re-use it.

 

The inside is clean, if this clears it up, i will get a new one.

 

Misfire codes seldom point to ignition system problems. Rather, the misfire occurs due to an insufficient fuel mixture ... which most often pointS to maf sensor but could be a misinstalled air cleaner.
