Need help

I have a 2015 Dyna Fat Bob & I'm experiencing stalling issues as I'm slowing to a stop & downshifting into 1st gear. At the same time the bike is idling at 1200+- rpms when first started & takes a good 30secs to 1min to drop down to normal 1000 rpm range. I have already replaced the IAC. Any help would be greatly appreciated.

Check for codes. Could be the CPS or vehicle speed sensor, but don't just go replacing stuff until you can diagnose it.

On the top of the Throttle Body there's a 1/8" black vacuum line. Make sure that it's still connected to the TB and that it doesn't have a split in it.

It sounds like the speed sensor. Pull it out and check for sludge. Wipe it off and replace it. You might also want to check the fuel lines insode your gas tank. They get a little pin hole in them and your fuel pressure drops off.
