2011 ECO Shudder - Honda Pilot

Dawg · 10-14-2011, 08:49 PM

Have 2011 EX-L with 2000 miles that acts like it is mis-firing or trying to shift between gears whenever I try to maintain a constant speed. Dealer had it for about a week and considered transmission, EGR valve and tires before changing out the rear motor mount(s). Problem still exists although not quite as drastic. Anyone else encounter this? Suggestions on diagnosis?

What MPH speed?
What Engine Revs?
What happens if you say shift it into 3? Same thing or different?
Is Eco coming on?
Wondering too about the TC lock up speed.

2011 Pilot-Biggest Complaint

Speed has been approx 35, 39, 45, 55 and 60. Have not paid close enough attention to RPM to say what they are when it happens. Will have to try shifting into 3 as I've not done that. ECO comes on although the shudder may happen when ECO does not show to be on. It seems to happen most often just before ECO comes on.

Be advised that the engine is in ECO mode before the light comes on.

It takes a few seconds to register. My 2010 is the same way.

By the way....Does anyone know what happens in 4 cylinder mode.......

Will that turn the ECO light on or does it only come on in 3 cylinder mode?
