  1. Not to familiar with this vehicle but I would think if you have 4 separate coils you could swap one the good cylinder coil with a bad cylinder coil and see if the weak spark follows the coil. If it does, replacing the 2 bad coils should solve the issue. You could also do this with the spark plugs.
