Hello everyone, I was driving back home with my Armada about 50 mph and the service light started blinking and the truck started shaking weird for about 30 seconds.
Does anyone know what the cause is I never had this happen before
The truck has 130K miles
Appreciate any help

Plug into the OBD port and pull out the code. Could be an ignition misfire(bad spark plug or coil). Let us know what you fiond.

Pulling the code would definitely help.
Did it revert to driving fine again after you turned it off and on?
