If i'm miss fireing that should set off the OBD light right?

My 04 Rubicon started shaking violently at stop lights, idle and so on last night. While moving and at higher speeds it sounds kind of odd and I can feel that something is not right, but its at a standstill when you can hear and feel something is completely wrong.

I'm assuming its either a broken motor or trans mount or I'm miss fireing. Problem is, is that its Zero here in chicago and my hood is literally frozen shut at the moment.

I would think if I'm miss fireing that it would set off a light correct?
I have no check engine light.

Take it somewhere to check it out yourself(heated garage at someoe's house).Motor or transmission mount would take 5 minutes to check.Sometimes codes don't go off.What do you hear and feel at a standstill?Misfire you can hear from the back when someone revs the engine.

It's really hard to tell because the damn thing is vibrating everything on the inside that it is difficult to pinpoint. I got out and listened from the back and it doesn't sound bad. It also doesn't seem like its lost any power. I'm hoping its a mount!..
