    Changes motor mounts twice and still car lunges and motor moves excessively when put into reverse or drive especially when engine is cold. Can anyone help?

    Sounds like idle is way too high .. especially when cold
    Don't know for certain the causes.
    It could be any number of things
    Throttle position sensor, associated wiring??
    Idle air control valve, stuck??
    Faulty fuel regulator??
    Crank sensor?
    Cam sensor?
    O2 sensors?

    Of course, never change parts without properly diagnosing the issue
