Hello guys.
I'm pretty new to the whole diesel world and even newer to the 6.2 world im on a learning curve.
I have an 86 j code that seems to have an excessive amount to vibration at idle, but it seems to go away when throttling up?
ideas of what this could be?

Air in the fuel, put a clear hose on the return line.

check that balancer for sure. Bad balancer=broken crank.
