Hey guys,

Every once and a while I'll boost to 5-10 pounds, and let off ... the car will burble along and go rich (12-13-14 AFR) under no throttle for as much as 5+ seconds (unless I get back on the throttle) before showing a full 21.0AFR like it should under no throttle on deceleration. It feels as though I still have the accelerator pushed slightly as well when this is happening.

Is that throttle hang? Will it cause any problems being that rich under no throttle (plugs, dilution of oil with fuel, etc.)

Is there any fix for this?

Fully built motor, every bolt on, stock IX turbo .... Forge DV btw, for reference.

ZB.
