Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Soul. It sounds like the iridium OEM plugs may be causing an issue due to differences in the gap or voltage needs compared to the copper plugs you replaced them with. Iridium plugs are typically more efficient and have a longer lifespan. However, if the vehicle's electrical system isn't supplying the proper voltage or there is an issue with the ignition coil, they might cause rough running, cutting out, or even headlight flickering. This could indicate a problem with the charging system or voltage regulator, especially under load when accelerating. It's worth checking the spark plug gap, ignition coils, and electrical system to ensure everything is functioning properly.
