'99 Lincoln Continental, Ignition Coil Problems
I own a 99 Lincoln Continental, I believe that one or more of the
ignition coils are breaking down but I don't know how to tell which one(s).
I used a multimeter to check them against a known good (new) one but the
readings are all very close. How do I isolate the bad actor(s).... Roy
The easiest way? Connect a computer scan tool to the computer and watch
the misfire monitor information from the computer. Each time a cylinder
misfires the computer makes a note of it. Its a real fast way to
pin down which cylinder has the problem. If the ignition coil is acting
up enough the computer will turn on the check engine light and there will
be a diagnostic trouble code in the computer that will flag the offending
cylinder. There are other means, but if you dont know what youre
doing you can get yourself in trouble pretty quick.
