My ECO light was always accompanied with varying levels of light vibration that I have always associated with the car going into either 4 cyl mode or 3 cyl mode. I am driving now with my foot almost entirely off of the gas pedal and I still can not get the car into eco mode unless I am going downhill. If it does go into eco mode, it is usually for a split second. I will feel the hard shift (hiccup), then eco mode light will come on. A split second later the eco mode will go off accompanied by another hicup. This happens contstantly at cruising speeds with cruise control on or off while on flat roads.Just curious what you mean, because the ECO light is not VCM. From what I understand, the ECO light has nothing to do with hardware... just lets you know when your driving style is "ECO". VCM is supposed to go unoticed. There's no indicator to us when VCM is shutting off or re-firing the cylinders.
actually, not really. Lengthy discussion and proof hereUmmmm...yes there is....that is what the ECO light is showing you. Going from 6 to 3 cylinders in my '06.
No sir, the ECM light is not directly linked to VCM operation.Ummmm...yes there is....that is what the ECO light is showing you. Going from 6 to 3 cylinders in my '06.
