Testing ignition coils?
 
is there any way of testing our coils to see if they have failed? i know that you can use an ohm meter to test some of the older ones, but does this apply with ours?

With a meter you are testing the coil windings for shorts.
Can you test for this... yes.
But if a coil is dieing and producing weak spark, you'll likely still read resistance on the coil.
Now if the igniter is bad... there is nothing (that I can easily think of) to bench test that, and unfortunately, its a likely component to fail.

Best way is to use a timing light to gauge against the other coils and see if one is weaker or more inconsistent than the others

Or save yourself an hour of pissing around and just buy a new set ( $120 or so ) :)

dannobre: so you get paid $120 an hour? :p
