A simple light failure wouldnt decrease fuel economy... perhaps the switch is bad, or has a loose wire.

SOURCE: My 1999 Honda Accord sedan

there can be many reasons for this. clogged air filter, clogged fuel filter, old spark plugs. if you do a tune-up and still the same problem, there are two things you can change, that will be the o2 sensor, which regulates how much gas and oxygen to combine for combustion, or the less likely one would be your etc or engine temperature control, which when bad for some reason also makes your car waste more gas than usual. but o2 sensor is MUCH more likely to go than etc sensor. hope this helps, goodluck

Vibration at highway speeds when echo light is on, 2011 Honda Accord?

is the vibration in the steering wheel (front wheels need balancing) or through the seat/floor? (rear wheels need balancing).

if the vibration is speed specific the abovewill be true, if you are sure its connected to the eco light then this is becuase the car is not firing all cylinders to save fuel. I would get it tuned at a dealer if the vibration is really that noticable

The eco light is always on

Hi there:
The ECO light comes on when the engine is operating in the peak parameters for best fuel mileage (economy). This is based on engine load, transmission gear, vehicle speed, and engine RPM.

Keeping in the parameters to keep the ECO light turned on when possible will gain you the best fuel mileage.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Multi cylinder misfire , check engine light stays on and at cruise speed when the ECO light should come on there is a roar from the engine . Its 2006 Honda Odyesse with 69000 miles

Take it to an auto parts chain store that will do a diagnostic scan for free. If the check engine light has come on it will have set a code in the computer and they can tell you what it needs.

ECO light on at low speeds

Yes, that is completely normal.   The cylinder deactivation feature is designed to activate based on a combination of throttle position, and engine load.  It really has nothing to do with the speed of the vehicle.
Enjoy your ride!
