FB25 - 2.5L Non-Turbo (2011- 2018)
I have a 2012 Forester with the FB25 NA engine. I'm getting a very sporadic P301 and P302 codes when accelerating at highway speeds, clear the code and it goes away, drive another 1000km and it might come back again.
I was going to check the coil packs first to make sure that they're still good...
