a few months ago i got a 0304 DTC which means there's an error associated w/ the knock sensor. i cleared it a few times to see if it would come back and sure enough it did. I've also noticed that my gas mileage really sucks. i get 17mpg city and 22 highway. Now, I'm not sure if the knock sensor problem is causing this. here''s what i got so far: resistance between knock sensor and ground is 550k ohms ( i actually took it out and tested the knock sensor itself), all the harnesses and wires test OK for continuity. Noticed that only one wire goes into the knock sensor even though there are initially two pins at the harness. I still get the error code after driving for a few minutes. Please help. Also, what kind of gas mileage do you guys get (everything stock)?
