my KA has been running like major crap lately and i just check my diagnostic code right now and its throwing knock sensor code. now ive had problems with knock sensors on other cars before but none of em showed any real symptoms, sometimes i couldnt even tell the difference.
here are the symptoms i have now
-Black smoke
-wont hold idle at times
-boggy/hesitant at time
-really bad mpg

my question is will a bad knock sensor really mess up performance that much? any help is greatly appreciated
