Okay thanks very much GD I just order my access port and I pulled the plugs today and I don’t think they have even been switched in their whole existence of the car they were black on the tips like carbon build up idk if that’s what it is but that was the condition I didn’t start the car as it got to late but will start up tomorrow morning  

Hello everyone I changed the spark plugs I started the car and it no longer had the check engine light on and idles fine but I will not be driving my Subaru until my access port gets here
