Is it common for the wideband to go from cruising at 14.0s then when you let off of the throttle it goes rich like into 12s?

No it should not. When decelerating it should go fully lean.

Sorry I should have been more specific.

Yes it does end up going to full lean with no throttle but just right as I lift my
foot from the pedal if I was just cruising, the wideband will go rich for a second
then all the way lean like it should.

I was trying to chase the spot on the map, just thinking it was really rich on the
lowest fuel lines when looking in 2D. But, even then when pull a bit of fuel in that
area it still will get rich right after I left off throttle.

I wouldn't worry too much about this as this sounds pretty normal.

what is your version ?

Okay thanks Spunkster.

I will have to check when I get home on the Version, I do not have my laptop with me.
I am pretty sure it is up to date though.

I have had this going on for like 2 years or so. Never really worried about it I was just
curious if anyone gets the same thing.

I'm using a PLX wideband, and I also get a blip towards rich before going to "AIR" when letting off the throttle. Just sharing as a data point.

this is fairly normal. It's basically the opposite of tip-in enrichment. Tip-in is when you quickly add throttle, the engine will naturally have a lean spike, and that's why tip-in enrichment adds a little extra burst of fuel for when you quickly add throttle. Quickly reducing throttle has the opposite effect; a quick rich spike, but there is no way to adjust for that and really no need to adjust for it either because it is not dangerous for the motor.

Thanks guys!!

I am glad I am not the only one.
