Default truck idles wayy down when stoping

When i come to a stop really fast somtimes my truck will die, if it doesnt die it goes really low in the rpm's. It idles perfect once your stoped just not when your stoping.

not likely, Maf isnt used much down low. Do you have a log of it. Is it tuned by you it looks like. What all has been done in the tune, can you attach it or perhaps a log.

I have the same problem. I'm convinced it's an air fuel ratio issue. I've logged so many rafigs and rafpns that it's not even funny.

add a little bit to the throttle cracker table, except for the 0mph column... Adding too much to that table and you will have cruise control, to little and it will stumble/stall
