I have this car roughly 3 weeks. Car ran very badly and Knock sensor was replaced. Also changed fuel and air filters. Car ran great. Replaced PCV valve but even though it was plugged Solid I felt no difference in performance. Yesterday I replaced the transmission filter and added 2 quarts of Dexron 3 to fill tranny to correct level.
Today a CEL came on and it is probably the same code as last week: Catalyst. I noted that there was quite a bit of CV Joint grease on the cat. Can this cause a CEL?
Also I found a broken vacuum hose that goes to some gizmo on the passenger side of the intake manifold. It appears to actuate a diaphragm. After putting the hose back on the power steering now feels Fantastic but the engine remains sluggish. It does not run as badly as it did with the faulty knock sensor.
I know I gotta pull the code but can anyone suggest what else I should check?
This "gizmo" isn't the EGR correct? Never worked o a Subaru and have no manual so I have been winging it.
ANY Suggestions as to what other troubleshooting should be done is greatly appreciated.
