A knock sensor is simply a microphone that is screwed into the engine block. It is there to listen for pinging or engine "knock" that is caused by poor fuel or extreme load. When the computer hears the knock, it retards timing, which in turn reduces the tendency for knocking, however, it will reduce power to a certain extent as well. It is possible that a faulty knock sensor can be telling the computer to ****** ignition timing too much, it is also possible that there is a mechanical problem within the engine that is mimicking the sound of knocking and retarding timing as well.

The exhaust manifold is right there as soon as you open hood , first disconnect neg batt cab, then jack up car remove bolts that hold pipe to manifold together , unplug any o2 that is in the way and that could get damaged. now from the top take shield off then take manifold bolts out. you might want to spray them with pb blaster and let set a few hours sense exhaust bolts love to break. Remember to use new gaskets installing new one.

needs looking at because it could be switch that allows it to turn on if sufficient gas is present ,or a problem with the clima compùter ,but to do anything you will need the special machine to empty the system then check things out so take to an authorised AC garage ,because these systems are a potential accident and you could lose a finger with frostbite in a matter of less than 2 seconds .therefore i will not tell you how to look for a soloution because of the dangerous nature of playing with air con
