The starter has no control on the spark so that money is wasted. Take it to a garage and have it checked out with the proper machin Check the coil packs

Yes, All Subarus are "wasted spark" systems where two cylinders fire at the same time, but only one is on the compression stroke while the other is on the exhaust stroke, thus the spark is wasted.

well it will be your coil pack that is a wasted spark model 1 coil fires 2 cylinders at a time notr one

Time and tide waits for none

what is old wasted if you not focus in your studies
