Default Low RPM missfire Help

Hey guy
bought an 06 fxsti put 800 miles on it and noticed a little miss. Its now becoming worse. When I go to leave a red light once in a while it will miss at the right time as I go to feather the clutch and the bike will stall. It also backfires and pops a lot as I decelerate. High rpm deceleration sounds smooth as I get lower in the rpm range it begins to pop like crazy.
I threw new plugs in it yesterday with no difference. I also had the check engine light on for about 30 miles a few weeks ago and it was a loose plug boot on #1 cylinder. Could it have hurt the coil?

Sounds like it could use a tune.

if it is an EFI check the fuel line in the tank for leaks. take the fuel cap off turn it on and listen or if you have the equipment check the fuel pressure.

Check the throttle plate. The shaft on my 04 cracked and caused all kinds of problems.
