Sounds like very low throttle pre-detonation.
Double-tripple check your EGR vac lines. (proper routing)
A wide open EGR at idle will cause pinning at very low throttle.
In particular the DPFE:
The Lower/larger/longer hose on the rear port
The short smaller diameter on the front port.
And the EVR (EGR actuator)
