A small rip can suck air making for weak mixture hitting the cylinders - misfire.
The rubber intake boots may be an issue, for sure.

As far as the coils go, I would think that it would almost be an impossibility for coils 1 all the way through 6 to go bad at the same time. I really don't think it's the coils but then again, I'm not sure.

One thing that I do notice is that when the car is cold, it idles a little rougher than when it's warm and if I don't allow it to warm up for a while and immediately start driving, it will sputter. It's even stalled once or twice since this started. When it stalled, it was because I didn't let it warm up.

Does this still sound like an intake boot to you?

By the way, thank you, for helping me.

This is great to know and I will certainly pick one of these up tomorrow.
