hi i have a 2010 wide glide went for a ride today bike surged at 100kms so i  pulled over to side of rode and bike was idiling way to high keep riding then fouled plugs, pulled plugs out and they were black put in new ones ,same thing happend changed fuel new plugs again and bike is idiling way to high , any help would be great thanks,ps cant get it looked at till later in month bike shops busy this time of year

Broken wire on the MAP sensor or IAC could be shot or just needs a clean.

ok thanks ,,, i am going to sound dumb but here goes lol wich one is map sensor .and when u say IAC MAY need clean wich one is that its my first harley and 1st ever problem thanks for ur help

MAP sensor is on top of your throttle body, about halfway back.
IAC is small motor on top of throttle body directly behind AC assembly.
Check all plugs and wires to the TB.
Check wires and plug going into bottom of coil also.

ok thanks will un plug all and make sure there all clean in plugs ect ,thank to all will let you know how it goes once again thanks for ur time.

You could try to clean the IAC motor with a spray can of injector cleaner (with the plastic straw type nozzle )

Take off the air cleaner cover and filter , and in the top of the throttle body a couple centimetres in there's a wee hole in the top.

Spray the nozzle in there, careful not to splash the paint etc ! You'll see black carbon/ crud come down

Then spray up the same hole with CRC/WD40 etc , mop up and reassemble the air filter

I put up a post years ago about doing this to a 2006 Dyna , but I did ultimately have to change the IAC motor.
