venting to intake and still very rich

[claymanTSi]

well i noticed this a few days ago, when i get off the throttle and let the bov vent, the car gets very rich, like so rich theres only the very last green led lit on my gauge, is this normal. I know it happens when venting to ATM but should it happen when vented to intake

claymantsi, let a pittsburgh guy help another pittsburgh guy out. when you are not on the throttle, the o2's cycle....so the reading is not accurate. the only time you are going to use the air/fuel gauge is at wot

p.s. did you hear about the local pittsburgh area meet?
check it out

That's not true, most AF gauges at WOT will read full rich so that's the main reason they are useless.

When decelerating the ecm should cut off the fuel flow and the AF gauge should read very lean until you push the gas again.
