My car is getting the code 23 for the knock sensor. But when i changed the o2 sensor it was white which means that its running lean. Could it be possible that the knock sensor is faulted and causing my car to retard the timing when its not needed....which would make it run lean? Could there be a ground problem somewhere around the sensor? The engine is a swap. Also i am hearing a weird almost knocking noise around the altenator...whats weird is that it only does it when it idle's down...if i turn the wheels and make it idle up it goes away. What is it and could it possibly be related to the knock problems. I need help here guys before i let some shop overcharge me trying to figure out a simple problem.....locating the problem can get expensive.
