Happened twice since , this time the engine light went out after a couple miles of driving.
So far only happens in the morning when i start the motor and put it in reverse.
The motor rpm's drop for a 1/2 second and the engine light comes on.(feels like its robbed of fuel)
I will go to the dealer if the engine light stay's on again.
Exactly what mine does, almost. Mine does it on cold startup as well, and the light will go out on its own after a few key cyles but doesnt have to be in gear to do it. It will stumble for a second and then run perfect.
It is very infuriating for me, Im a mechanic for a living so I know they are just not putting any effort into it. Even when the light comes on, it is not running rough at all, and day to day it runs great.
I will get the build date tonight and post it up, its an early one I know that...
