What does DFI mean on a Kawasaki mule?
troubles occur in digital fuel injection system (DFI). If the warning light comes on, have the DFI system. checked by an authorized Kawasaki dealer.
What’s the RPM of a Kawasaki Mule Stall?
Then when it settles down, it idles very low and stalls eventually-sometimes it’s almost immediate, sometimes it takes a few seconds, and sometimes it’ll idle at 450-480 RPM (using KDS software) and then just quit.
Are there old style sensors in Kawasaki mules?
There are still some of the old style sensors in the system, so be sure you do not get #21176-2096. Get one and try it before you replace all of them. The other really critical issue is the fuel. If you run anything but LL100 for aviation, you will have fuel injection gumming issues.
Where is the throttle control on a Kawasaki MULE?
The throttle control you step on only controls the sub-throttle valve which is upstream of the main throttle valve.
Why does my Kawasaki 4000 engine not idle?
We ran into this back when we sold Jet Ski watercraft. On the early FICHT 1100 STX DI (direct injection), if we held the throttle at anything but idle, turned the ignition on and then started the engine, it would not idle at all.
What causes a Kawasaki 4000 mule to stall?
If the main throttle position sensor is read as being open when the engine is initially cranked up, being that the ECU assumes that this is “idle” or zero throttle input, and then later on the throttle is released and the ECU gets confused. Confused enough to close the sub throttle completely which drops idle speed to very low speeds.
What’s the base idle speed on a Kawasaki MULE?
On another Mule in testing, we opened up the sub throttle’s stop screw to achieve 800 RPM base idle speed. This was done by manually holding the sub throttle closed and then adjusting the stop screw until 800 RPM was seen on the laptop. Then locked the screw down.
What causes idle surges on a car ECM?
Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges.
The throttle control you step on only controls the sub-throttle valve which is upstream of the main throttle valve.
