cars a little shaky when on .. ?

could it be a vaccum connector? or something else?

Gonna need some more detail. Does this occur in gear? Does it occur when at idle? etc etc

mine does the same thing too when im in gear. the whole car vibrates but if i put it in neutral or reverse it stops the shaking.

my car all of a sudden started nd shut right off when i tried to give a little gas so come to find out i needed a new ECU .. got it installed today and check engine light comes on giving out a code i believe either P1626 or just 1626 one of them which im not sure what they are .. took it for a ride around the block .. let it run for an hour nd everything seemed to be fine until i drove it home and i noticed when idle its shaky .. then i put 1st gear nd take off its fine .. when switch to 2nd it doesn't give as much power as it used to .. any ideas ?

My car did the same for a while and still does it slightly. First thing to do is to check for all vac leaks. Once i replaced my MAF sensor, this went away.
