Im having a problem with my Impreza.
Its running fine under steady driving and idling fine.
I replaced the maf with a new one to rule that out also.
But when accelerating hard, it seems to hesitate and pull timing at about 5000rpm and upwards.
It is still boosting upto normal levels on the Defi guage.
Also no check engine light.
Is it possible it could be the o2 sensor? Doesnt seem like the knock sensor symptoms i had one before
