Simple question

Anyone know the reason for the anoying "high idle under
de-acceleration" on a modded MAF caf?

I'll come up to a stop light, and for like 30 seconds the idle will pin at like 2,300 RPM then shoot down to normal.

Yeah, thats a good question. Except mine only stays at 1 grand or so for 5 to 10 seconds.

I was originally thinking that it may have been something to do with the DFCO, but that guess was pretty far off base. So anyone else have a few suggestions?
