Another miss thread

[Zeek]

So i started my baby up this morning and it started to blow some light blue smoke. Not only that but when I started driving everything felt normal until i started going up a hill in OD. It started to shake like the tranny was going, so i turned down my radio and the engine sounded louder and choppier than before. So i said to myself, oh great my engine is missing. Got to a stop sign and it shook like mad, unluckily this is my only vehicle that is/was fully driveable. Any ideas what to check for? I have a video but it isn't a good representation, it didn't feel like it was missing as bad when i got to work this morning.
