    Probably the first step in this diagnosis will be to get a scanner that can read cam retard and see if the timing is set correctly.

    I've heard of worn distributor gears triggering this code.

    No, can't use a timing light on these.

    I'm pretty sure a good Snap-On scanner should be able to do it. Cam retard should be between -2 and +2.
