94 5.2L Magnum running rough

Thanks @AJ/FormS , that's some good tech.

To follow up: I replaced the crank sensor just now and it's running fine again. Didn't get a chance to drive it yet due to graduation parties (and a 2010 Charger parts car clogging the drive way).
It idles good and the exhaust isn't stinky either. Let it warm up fully and it seems good. That's two bad crank sensors... they seem to last about a year and then POOF!

Thanks for everybody's help.
