Was wondering if anyone would be able to help me find where the knock sensor harness is located....It has over 100k miles on it unless it has been changed before. And how can I check to see if its bad or not, and where can I get a knock sensor/harness for a good price? And if my knock sensor is bad, would my gas mileage suffer a little bit due to retarded timing?

 

Again stickies.

Mileage may/may not suffer.
