Question

HOW MUCH TROUBLE IS IT TO REPLACE THE KNOCK SENSOR.

Answer
being that your vehicle is a 6cyl it's gona be a little more difficult than a 4cyl. you would have to take off certain parts of the engine to access the sensor since its internally installed in the block unlike a 4cyl which is just bolted on the back of the block under the intake manifold
