Fault code P0505
I've got an '06 Street Bob that has been punched out to 113'. It has the stage 2 kit and VH big radius pipes. I've been having problems with my EFI. I ran the Self Diagnostic and got the code P0505, and the part number 34327-06. I looked online for the part number and came up empty. can anyone give me any help on this?

p0505 loss of idle speed control
a lose of idle speed control does not necessarily imply the IAC actuator or wiring has failed. It can be caused by a number of conditions such as a intake air leak improperly adjusted throttle stop or a misfiring cylinder.
diagnostic tips. leaking injectors will cause fuel imbalance and poor idle quality due to different air/fuel ratios in each cylinder.
Vacuum leaks in intake
Contaminated fuel
Excessive oil in crankcase (oil sumping )
TPS reading greater than 1% (possible throttle cable maladjustment) or battery voltage reading of less than 9 volts or a VSS greater than 0 will disable idle speed control
Loss of battery power to ECM pin 31
Good luck

Do you have any warranty on the 113 build. Start with the easy things first check your battery is it fully charged. Then I would check your manifold flanges for a air leak by spraying some engine start around the manifold and listen for the revs to jump.
