    Q:
    How should the PROM be removed from the Engine Control Module to prevent damage for the 1985 Buick Regal? Posted by Hrvoje I.
    A:
    Using a rocker type PROM removal tool, engage one end of the PROM carrier with the tool's hook end, press on the vertical bar, and rock the engaged end of the PROM carrier upward. Repeat this process for the opposite end until the PROM carrier and PROM are free from the socket, ensuring that the removal tool is used to prevent damage to the PROM or socket.
