Nick here, have a 2011 wrx wagon. Absolutely love the car. I have been seeing some issues lately (no mods this my daily driver, keep the 68 mustang for all that fun stuff). Ive been working on cars for a while, but mostly rest-mods and such, first venture into the world not turbo 4s, not more tunning carbs through sound car makes anymore i guess.
I truthfully bought this car to avoid spending my weekends working on it. But I have seen the same 2 codes come up and the dealer has basically telling me its 1500 bucks to guess what the problem is without exactly being sure what caused the issue.
P0301 and P0303 cylinder missfire.
Dealer did roughness test, slight roughness in both cylinders (~1-2%). cleared codes and set if it comes back then they will have to take the motor apart for 1500 with hopes that all it needs is a valve job
Car has 54K on it, going to change plugs, etc as per the 60K major service. Any other suggestions?
Thanks in advance.
