I just posted a thread about the Dyno Day at Brauning tomorrow. An hour ago, my engine light and atts light come on. Pul the CEL, 23, Knock Sensor! Atts was also flashing when i pulled the CEL, but i think thats just because of the two computers being interlinked or whatever. So i know that the Knock Sensor is located under the Intake Manifold, just below the head, in the Block, between cylinders 2 and 3! Now the big problem is, can i get to that sensor with out pulling the atts out or what. Anyone have any better way to replace this? I have the knock sensor from the blown motor that i can replace it with. Please help, im trying to get this done so i can get on the DYNO!!!!
