The knock sensor (if underneath the vechicle)is located above the oil filter just to the left, behind your antifreze return. It is a pain to get at, only one screw takes a couple hours to reach it. I filed (narow) down and old wrench because i didnt have enough room, once loosen i did it by hand. you can see it from the top of the motor between the 2nd and third fuel injectors (you can only see the screw you CAN NOT see the knock sensor). Have fun! ALSO IT YOUR CAR IS OCCASIONALLY STALLING RUNNING RICH AND SOME BLACK SMOKE WITH YOUR RPMS JUMPING AROUND. IT MAY BE YOUR TEMPETURE SENSOR EVEN THOUGH THE COMPUTER READING SAYS KNOCK. ITS $21 COMPARED TO $180 AND IT WAS THE CASE FOR ME. COUPLE MINUTES COMPARED TO SEVERAL HOURS. THANKS
