my went at about 140K. unfortunately i replaced with ap1 which were $$$.

 

Last update!

So it turns out it was like everyone said. Coil pack #3 went out at 93K miles. Shop replaced it and she is running smoothly again. Since one of them failed I suspect the rest will go out very soon as well and will be replacing them myself.

Thanks for the help

 

Good news! Relatively cheap fix.
