So ever since I bought my xterra about a little less than a year ago my check engine light has been on regarding my knock sensor. I want to eventually replace it but not very sure how to go about it. some people have said to relocate it, forget about it, or just remove it completely. so what do you guys recommend me doing? Also is this something that will effect my car in the mean time as far as engine wise or not? I'm kinda familiar with what i'm doing but need a little extra help!
