Coil testers are not always 100% reliable, the best test IMO is to substitute a known good coil and go for a drive. If you have an intermittent spark problem and haven't done it yet, before you condemn a coil, check the wire feed from the ignition switch for intermittent shorting. As cars age, it's a classic problem where coil feed wires are enclosed in a grounded metal shield.
