Knock while idling

[jd21]

Im getting knock at idle 2.8 deg its not much but i cant figure out why i have not been able to do a pull yet i am waiting on a wideband. The sensor is brand new oem, should i just pull timing when it hits knock at 4500 rpms the knock goes away at 4700 rpms

You should also update your profile with car info and mods, how much help can we be if we don't even know what kind of car you have?

your o2 looks , also you have a knock sensor malfunction dtc, i would replace that if I was you

ok thank you i just got link ive watched all the videos from ecmlink.com just a little bit conusing i never really tuned before. Would the front o2 be bad reading that low of voltage? Why would the knock sensor read bad when i just replaced it with an oem one, it was torqued to 17lbs

o2 cycles from 80 to 20, and thats what your dtc said knock sensor circuit malfunction http://www.dsmtuners.com/forums/tun...0-p0031-knock-sensor-circuit-malfunction.html

Knock sensor shouldn't even show up until the set parameters are met. IE./ 2200 rpm and throttle position > 35%
