Question about 2004 Harley Davidson FLHTC - FLHTCI Electra Glide classic
When started, the idel is real high, when running engine sputters and pops like it's bad gas, replaced gas, added fuel injector cleaner and gas treatment. When engine is idleing, I disconnect the throttle position sensor and it slows down to a normal idel, but when under load it resumes sputtering and popping. Diagnostics show no codes, replaced shredded breather tubes, new air filter. I suppose the next step would be to replace the throttle position sensor, but a lack of codes in the Diag mode is stopping me from doing so. Thanks in advance
Hi John, high idle on fuel injected models can be casued by a faulty IAC valve located on the top front of the induction module. It has either failed electronically and needs to be replaced or mechanically getting gummed by contaminated engine blow by. You can try cleaning the unit by removing the air cleaner and backing plate, unplug, unscrew and remove the IAC. Using carb cleaner and " LOW " volume compressed air to clean the metal pintle and shaft that is spring loaded and has an operating length of just under 1 inch. Aventurous souls who did not heed the low air warning have launched pintle and spring into parts unknown. There is no guarantee this will work but worth a try since a new one is $50.00 Good luck and have nice day.

SOURCE: hard start, trouble idleing
Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install new stock spark plugs. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. This process should get you back on the road.
Please rate this solution. Thanks!

well, if plugs are wet, try placing plugged in spark plug on the block, turn ingine, should spark blue. orange no good, none no. good lol.do both plugs and wires.if one works and the other one doesnt, you need a new plug.if both no good, having electronic ignition, most likely the coil is toast (make sure its plugged in good, cables and wires)

SOURCE: High Idle On Start-up.
Most fuel injected motorcycles do start up in a "fast idle" mode. Although I don't know much about fuel injection on Harleys (H-D will not tell you much about it unles you are one of their technicians), I don't think the system is equipped with an engine temp sensor. Since the crank case sensor get it's pulses from pockets cut into the outer edge of the left side flywheel half, the sensor will have oil on it.
