    hey guys is anyone else had or experiencing the same problem as we are
    it happens as mentioned going up a long slow incline generally losing power
    to the point where it shakes and then stops
    so far mechanics 3 of them have suggested from lifters (replacing them), to
    oil flushes @ $150 each (did 3 of these, now flushing the oil ourselves when
    the problem increases)
    we have replaced fuel filter, fuel pressure regulator (most improvement so
    far), spent $$$ on oil flushes (mechanics suggest this the problem, although
    it fixes it short term it has never been a permanent resolve
    we have come to the conclusion it is definately fuel related and at this
    point we are considering replacing the fuel injector o rings and the
    insulator on the underside of the caps

    please if anyone has any suggestions we would love to hear from you.

    I would next check the fuel pump pressure. Lifters and oil changes??
    I'd find another mechanic. I agree that fuel or lack of it could be
    the problem. You may want to use a good fuel system cleaner like
    Techron concentrate (Wal-Mart ^-& dollars). That would clean up the
    injectors and intake valves. let us know what you find.

    Julie,

    I have no idea how prone Subaru's are to this but I recall a car I
    worked on years ago with a complaint of losing power only after long
    moderate pulls and it turned out to be carbon build up on the valves.
    Has anyone done a compression and/or a leak-down test on the engine?

  4. possible clogged catalytic converter - especially if this symptom is
    more likely or worse when car is hot or has been driven for a while.
    Also, I THINK I recall a fuel pump or fuel pressure regulator causing
    this too.
