Engineers design modern engines to run in a narrow temperature window where power, efficiency, and emissions all line up. The ...

As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...

It's easy to assume overheating is a result of long road trips or summer heatwaves, but when your engine gets too hot while idling, it's usually a sign of something deeper that needs immediate ...

First thoughts are that the stepper-motor (which controls the idle speed) is faulty. That would explain both the high idle at low engine temps and the stalling and stumbling as you roll to a stop.
