car will shake!!!!!!

when i stop the car it will shake bad with a low idle. i can press on the gas with the bake on an stick my idle back to 800-1000 rpms. but would any one know what this could be and how i can fix it. i have an auto-tranny and i think that might play a part. it drives me :crazy:

what’s your idle? normal is around 500-300 without mod, if it shakes bad at idle more then likely it’s your motor mounts have gone bad after 10 years of abuse, if u have a auto tranny it should be the front, but also check the rear too since that’s the closest to the fire wall and could be contributing the most vibrations, i think it’s connected also to the wall, but i don’t remember
