Possibly temp related? Maybe the IAC stepper needs to be adjusted? My temps typically climb during cruise and fall when slowed/idle.

I found the P0505 on my wife's 2007 sportster had a broken wire in the idle air control motor harness, you can get a replacment harness/connector from napa part # ec113 comes with wires and connector. (the wire breaks internally cant see from outside) its about $24.00 and problem solved on hers
Also her bike was doing the high idle skit for 2 years before ever setting a code!!!

Thanks for the tip JSDyna.

Long story short, the idle was really high,... again. Ordered the cable in hopes that this is the fix.
