You may even want to have them cleaned and checked professionally. One thing I would try is swapping the coils around and see if the weak spark moves with the coil or not. You may have a bad coil or plug wire. If the problem stays with the same rotor, then look beyond the coils at the wiring, connectors, switches, etc. Mark S.

I like Dale's suggestion on swapping the injectors.  You may even want to have them cleaned and checked professionally.  One thing I would try is swapping the coils around and see if the weak spark moves with the coil or not.  You may have a bad coil or plug wire.  If the problem stays with the same rotor, then look beyond the coils at the wiring, connectors, switches, etc.

Suggestion - to eliminate the injectors as "the" problem - swap the
rotor #2 injectors with the rotor #1 injectors.  Does the problem stay
with the rotor or move with the injectors?
