has any one resolved an issue with knocking sound on their vq30de? (sounds like rod knock) it happens when the car is completely warmed up , when it is first started up it wont start knocking un til it reaches operating temp, then after awhile it goes away? while in park it idles rough (shakes) i ve gotten p0300 done fuel trims tests in bank one i get -7-9% ect. short term guess the ecu is reducing fuel for a rich condition its running in open loop all the time. check all the sensors coils ect which are new plugs ect still cant find the problem , please give me an idea
