What happens when idle control valve goes bad?
If the idle control valve fails completely, it may leave the vehicle without a source of air to maintain a proper idle. This may result in the engine stalling while operating, and in some cases may result in an engine that will not idle at all, and stalls as soon as it is started.
What are the symptoms of a bad air idle control?
If the idle air control valve (IAC) fails completely; it may leave the vehicle without a source of air to maintain a proper idle. This may result in the engine stalling while operating; and in some cases may result in an engine that will not idle at all; and stalls as soon as it is started.
What does the idle control valve do?
The idle air control (IAC) valve is located on the throttle body of fuel-injected engines, where it works with the vehicle’s ECU to electrically regulate airflow to the engine to ensure smooth idling.
Can the idle control valve be cleaned?
Cleaning an idle air-control valve can keep you from buying a new part, but only certain idle air-control valves can be cleaned. The idle air-control valve must have a spring-operated valve for cleaning to make it work.
Where is the idle air control valve on a Harley Davidson?
Without plagiarizing his work, that writer basically referred the reader to a small valve just inside the throttle body and in front of the throttle plate (The idle air control valve). He sprayed carb cleaner up in there with the little “straw” that comes with spray cans, and all kinds of black crud came out.
When does idle become stable on a Harley Davidson?
Once the voltage is around 14v, the idle becomes stable at around 1000rpm. Would the voltage be the problem, or is it that when the bike is around 1000rpm the voltage is around 14v, and one doesn’t “cause” the other in the sense of being the problem?
What should I do if my Harley Davidson is idling?
Load test the battery too and if it is weak replace it being it idles normal once the voltage gets up there. Generally anything above 9-10 volts will run the electronics but there;’s always that exception. Thanks Glider, I’ll check all these things out. First, I’m going to find where that motor is and see if I can’t check it myself.
