Re: Slight high speed miss sometimes

["Gary H." <spigot2039@xxxxxxxxxxx>]

Some other things besides timing to think about, from a page about MP Electronic Ignition: 

High speed miss

   1. Check for loose connections or poor grounds.

   2. Check for dirty or worn spark plugs.

   3. Check for faulty spark plug wires or poor connections on new wire sets.

   4. Check the battery voltage at the ballast resistor. It must be no lower than 12.5 volts. This is especially important on cars with alternator cutouts or cars with no alternator. If the vehicle uses an alternator cutout, teat the voltage with the alternator turned off.
