1994 Mustang Cobra - Really need help!!!!

I was coming home from work today and at the last stoplight my car started shaking pretty bad. It did it bad in 1st and 2nd gear, and when I got into third, it drove normal, but the speedometer kept jumping from 0 - 40 (would stay on 0 but occasionally do the jump to a mph). The ABS light also kept coming on and off. Radio turned off completely, and when I finally pulled into the garage two blocks later it smelled of burning. It is a manual. Any help or ideas would be greatly appreciated.

I was doing some more testing on it. When I have it idleing an give it some gas, the response I get from it is a wave of 3 shaking/studders. (Giving a little gas, let off= da da da duhh, da da da duhh, da da du, and then goes back to idle state). Sorry for the bad language use, but thats the best I can explain. It still shakes more than usually in its idle state also...Thanks for looking...

That is a strange one.

I would guess it has something to do with the tranny, (captain obvious at your service:). Any crunching whne shifting, neutral is fine when in idle? Also sounds like some
