why does my car have a bad vibration to it in the engine? on 2002 Ford Focus

I have had it to 3 different mechanics and no one can seem to figure it out. It ideals high when i first start it, and i can hear the belt turning. I have put 3 different o2 sensors in it, mass air flow sensors.

CHECK ENG. LIGHT ON? DOES IT DO IT IN PARK OR WHEN DRIVING? HOW LONG SINCE LAST TUNE UP? GOING UP A HILL IS IT WORSE? DOES IT VIBRATE THE CAR OR FEEL LIKE A JERKING AS YOU DRIVE ALONG? MOTOR MOUNTS, PLUG WIRES, COIL PACK, PLUGS, INJECTOR(S). AUTO. OR STICK? AND WHY DID YOU REPLACE THOSE SENSORS?

yes my engine light is on, i replaced sensors because the mechanic said the computer was reading sensor was bad but it still does it. It vibrates all the time, in park, while driving, always. mechanic checked motor mounts also. It does seem to calm down a bit after I've been driving it for a little while but when i shut it off and start it again the vibration is real bad again. Thank you for responding!

ONLY THING I CAN THINK OF IS TORQUE CONVERTER IN TRANS. IF 3 MECHANICS CAN'T FIND IT I CAN'T EITHER, JUST SUGGEST SOME POSS. REASON FOR YOUR PROBLEM. ARE THESE GUYS PRETTY GOOD MECHS.? MAN,IT SURE SOUNDS LIKE EITHER A MOUNT (ENG. OR TRANS) OR SOMETHING OUT OF BALANCE. MAYBE EVEN EXHAUST HANGERS. IF WE ARE SURE IT IS NOT AN ENGINE MISFIRE!! GOOD LUCK.
