Hi everyone! Need some advice on something. My tuner plugged into my car and we noticed my ‘Knock’ variable readings fluctuating (0-5). This is only happening upon slowing down and going over speed bumps. Idk if my knock sensor is bad or is it the engine really knocking. I recently rebuilt the engine as well but I don’t hear anything or no knocking noises. I did some research and noticed many of my symptoms was a bad knock sensor, but I would like to stay on the safe side of things. I upgraded Cams (Tomei S2), and did not tune. Was just going through that breaking in phase, and is ready to Tune now. I really need your help if anyone experienced this. My Exhaust is also not in its best shape. Will replace soon, as I also assume the loud noise and heavy vibration from the Exhaust System can be affecting the Knock Sensor when the car is vibrating heavier at idle.
