What owners wrote
I was driving on the interstate at about 65MPH. Vehicle became unresponsive to the gas pedal input. Check engine (yellow wrench) light came on. I had to cross over to the right side of the road, while coasting with the engine at idle. Came to a stop and that's when I realized that the car was at idle and would not respond to the gas pedal. Turned off the car, and it restarted after a longer than normal amount of cranking. Check engine light was out. Car drove normally to my destination.
I was on onramp, vehicle slowed down, wrench light lit up on dashboard. Vehicle would not accelerate. I pulled to the side of the highway and restarted vehicle. Vehicle continued to do this for the duration of our trip.
