Can this be caused by a bad knock sensor?
Alright - so after reading the knock sensor write up over and over again - I am sorta stumped.
I have measured the resistance of my knock sensor, and its 560K ohms - which is within spec, however that's about the only thing I can check. I did a code reout on the ECU, and the only thing I get is code 14-06 which makes no sense so I think it's some ghost code.
This is what I experience - sorta sluggish acceleration below 3K RPM, and vibrations - very faint but still noticeable, as if the engine is firing slower if that makes sense, however its not misfiring and it's not throwing codes. My MPG has been dropping consistently over the past month. Acceleration after 3K RPM is a bit better but not by much; it gets up to speed fine but it just feels sluggish, slower than my mom's 01 V6 Accord Auto (3.0 Liter 200 HP).
Can that be caused by a knock sensor that is working intermittently even though on three different occasions (overnight parking, 2 hours after driving and immideatelly after driving) the resistance measured the same?

Try to tighten it with a wrench. After I replaced my bad knock sensor with a new one from ebay, the ghost code didn't go away so I inserted a regular wrench in there and tighten it a little bit, reset the ecu and the code never came back.

Did you get the same ghost code?

Well the sensor was my first suspect... but I suppose at this point I should consider it as working.
I suppose it could be the coils/plugs - the car shudders slightly in 2nd gear between 2.5 to 3K RPM, less shuddering at the same RPM range on other gears, and almost non existant at 5th gear.

Regarding the mileage , may be one of your calipers is seized ?

Just had the brakes done.
And yeah - I Am pretty sure bout that code - it got me confused too.
