New 2017 GT350 with 2500 miles. I was driving on the freeway at a decent clip and exited. As I slowed for the light, the idle got really rough, the wrench came on and it said check owners manual. It also threw me out of Sport mode.
I managed to drive it (very slowly) to a parking lot not too far away. I couldn't accelerate at all, just crawl forward at the rough idle. I got into a spot, turned the car off. Then just to check I turned it on again and it was good as new.
Anyone experience this or know what it might have been? I thought it was flooded perhaps but it recovered completely in the 5 seconds it was off, which leads me to believe it might have been a computer issue. It's been sitting for the past 5 hours at work, going to go start er up again to see if everything is ok.
Thanks for any insight.
