    1have any mods been done pipes air breather ecm downloads, 2have you checked for a vacum leak at the head to manifold union 3is the engine carburated or injected. the engine will pop at take off when the fuel air mixture is lean or the timing is off, your bikes timing and injection if injected is controlled by the ECM, if you have a carb then you might have a lean low speed circut or slow speed circut depending on the schooling and since you said it dosent happen all the time and the age of the bike Im gona guess its the manifold gaskets (o-rings) leaking

2004 FLHTCI high fuel consuption, Fast idle, engine sputters


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.

I have a 2004 chevy malibu classic. car ran out of gas and stopped. put gas in and tried too restart the car. car wont start but you can smell gas and wants too start but wont.


Hi, you may have it flooded. Try holding the accelerator all the way down while cranking the engine to clear the gas out. Let us know if this doesn't work, and thanks for using FixYa.

2005 ultra classic has developed a stutter when not under load. I recently used 87 octance fuel could the is be the cause


Using low octane gas I believe would give you pinging when a load is on the the motor. If you are getting misfires with no load, I'd changed spark plugs first, (easiest and cheapest to do at first). Secondly, check output of charging system to be sure enough power is available to operate ignition system.
