Get Knock Sensor Indicator in 1st 'round 2.5k RPM

I don't think this is normal, it's not even when I'm beating out of the car.

It happens occassionally when I'm leaving to go to work.


Has anyone else experienced this? And i'm not referring to people doin' 75MPH and getting knock - I would think traveling at a few miles an hour wouldn't warrant something like knock .

logs, mods, tune? You are missing a lot of information if you want someone to remotely diagnose the issue.

I would suggest contacting your tuner if the car is tuned.

Its just part throttle knock - at 2500 rpms your probably picking up engine harmonics or some other noise that is tripping the sensor - it does and will happen, plus its low load / low rpm. Really not much to worry about, especially if its occasional.

I get part throttle knock occasionally between 2500-3000 rpms around 60-90 load - it just happens and I don't worry about it.

Happens to me randomly too.
I've tried to recreate it again, but it seems to happen randomly.
Pretty much narrowed it down to my DP hitting something and triggering it.
