    . Check for codes.

    . Replace the Crankshaft Position Sensor, if the Ignition Control Module (ICM) you installed was new. A failing ICM was my first thought.

    . Replace the coil packs, if the problem persists.

    Check the ignition switch for wear, pitting, or melting.

    . Clean the main ECM ground.

    . Replace the Crankshaft Position Sensor.

    Have the ECM tested, if the problem persists.

    Yes, it's the computer. It has a large gang of wires going to it. GM likes to place them near the fuse box, in many cases.
