Yes mine will show knock when parked and I stab the throttle or while I’m driving and stab the throttle. I do not have stock drive shaft. I have a solid one piece.
What's your exhaust setup?
One other thing I've noticed with mine is it won't KR when the engine is cold. It starts to happen around 165-175 degrees. I'm not sure if the knock sensors are not active below that temp, or if this a potential clue?
Have you ever put a scan tool on it to see which knock sensor is reading the knock? Last time I did this it was the passenger side sensor reading all the knock.
