Changed Knock Sensor, and cleared the codes. Check Engine light staying off, so far..... 
Does the knock sensor have any affect on how the car runs, especially when cold? Is it a heat activated sensor? When the light was on, the car was VERY sluggish, until it was under WOT, but as soon as the car got to operating temp, the light would go off, and the car would run normally.

Once code 43 is tripped, you're system goes into limp-home mode... I think that means it takes off all the spark advance.
Guys... is that right?
