Does anyone have a problem with their knock sensor? My X is running terrible and the diag.reads knock sensor malfuntion. Could anything else but a defective KS cause the code to come up. I thought that if there was water in the gas causing it to run rough that maybe this could cause the code to come up. If I do have to replace it is it a difficult job? I've also heard of bypassing it with resisters. Is this common practice?
Standing by waiting to see if I have to replace it. Can't drive it like this.
