knock sensor problem... maybe?

[insanemaniac]

I've had the engine light on a few times now, and when I check the code, it reads knock sensor circuitry. In the past I've left it alone, because the engine ran fine even @ high loads, no knocking/pinging. Last two times the light came on, i left it alone for a few weeks and it went away. Now the light is on again, anyone know if I shoudl jsut replace the sensor since i've heard it is not the easiest thing to do. Someone help? and if I do have to replace... anyone have a good one for sale?

its quite easy to replace it, it just takes time, you just have to use your brains when puttin it back in.
