So I can’t find any forums for the legacy so this is my only hope, I have a p0011 code which is camshaft position timing over advance and i can’t figure it out. I’ve changed my oil, camshaft position sensors, variable timing solenoids and I even looked at the banjo bolt and took out the filter and it’s still on, my turbo won’t build boost and it takes a second for my car to reach higher rpm… help?
