While driving in open loop the AFR is a little lean like in the low 15's but when sitting and at idle the afr goes real lean in to the 17's, I have DFCO off correctly I think, does any one know what is wrong?

BTWI am reading off a AEM WB gauge.

 

You are obviously tuned for open loop at idle and your fuelling is incorrect if that is not what you are commanding. Your MAF and/or VE is not tuned correctly.

 

Think it is me VE...thanks

 

if the the AFR is fine at girst when idling and then tapers lean, look at your IAT, it could be getting heat soaked.
