Engine knocking at idle only when warm
#13
<------- gots the knock also. When im on the highway and i'm giving it about 1/4 amount of throttle i heard it, but if i go about half or more I dont hear the knocking... As for at idle, once I rev it goes away as well. but idk. its annoying tho

I think a good way to see if its a rod bearing is to unplug a coil pack or injector while its running to see if teh sound chages on a certain cylinder. If its a rod bearing a lot of times the knock will change or go away due to it not firing on that cylinder.
