So my code 52 is only coming on when its cold now. think that would be the knock sensor wire now?

That could happen with any of the three components. In order of likeliness: wiring; sensor; ECU

If you can get a used sensor for very cheap try that firs as it's low labor. The rewire is usually less expensive though but much more labor intensive. I would wait on swapping the ECU as that is very seldom what's to blame.

i was going to try the sensors them selves first until the last owner (friend of mine) said he just replaced them not too long ago.
