Mission accomplished based on the photos and post comments! Thanks everyone. It was a quick job like everyone mentioned on the 2.5L in my 1998 Legacy GT. Having a magnet tool helped in retrieving the bolt. My check-engine light is off and the car's power band seems to have returned. Still not as much power or quickness as a friends 1997 Legacy Outback (maybe the GT's weighs more than the outback, both are 5 spds?)

I have the same problem with my 1998GT. The knock sensor on the 2.5L appears to be tough to get to and not an easy job to change out or test. My Haynes manual indicates that quite a bit of the top of the engine needs to be removed, which includes the alternator and manifold assembly. Is there an easy/quick way to remove this sensor, one that doesn't require major disassembly? Thanks in advance.
