intermittent stall

I've got an 07 street glide, 96 incher with a stage 1, heavy breather air intake and rinehart 2-1. FI has been mapped, ran 9700 miles with no trouble. Just started an intermittent stall when the rpm's decrease (coming off a highway, slowing for RR tracks, stop signs). It runs great most of the time, great acceleration so I feel pretty good about the fuel delivery. Only thing I can think of is the computer module for the FI.

Any ideas out there from you guys that are a lot smarter than me?

May be the IAC, idle air controller, sticking. This could cause, if it closed down some during normal riding and struck there, the engine not to get enough air during this time.
Squirt some carb cleaner into the little hole at the top right inside of throddle body.
Might help if thats it.

Thanks, Gunny. I have an IAC with the fuel injection? For some reason I was thinking the computer controlled the gas/air mix. So this means the computer is probably telling the IAC to allow more air at lower rpm but it is sticking closed. Am I getting it right?

Thanks for the help!

This months AIM, American Iron Mag, has a good artical on Fuel Injection. Clear

And if the IAC goes to sticking, after it is unstuck squirt some silicone spray into the hole. Just a little for lubrication.

Try running some fuel system cleaner through a tank of gas?

Thing is, this area of the TB normally never, shouden't, see any gas. The IAC is in front of the troddle plate. Opens up a little to let air go around the plate when that is closed. May get dry sometime.
