Engine Racing Incident @ idle

Extremely cold weather
Truck running for 20 minutes when I pulled into the parking lot.

Stopped in Drive > right foot on brake
Sudden/wild engine race > truck tried to lurch forward.
Pressed hard on brake pedal & killed ignition.
Started again > normal

Drove home after work > normal
Reported incident to dealer & Ford Performance

take your foot off the gas....

Aftermarket floor mats...

If you were able to safely get a cell phone clip showing your foot on the brake and the RPM up like that im sure Ford would be very interested.....

FYI sometimes my larger shoes/boots I have been pushing on the gas pedal as well. Could be hung up on the floor mat. Could be the truck and not you or your matts keep an eye on it.

sensor fault? > related to extreme cold
right foot on brake > floor mat/gas pedal not in play

I thought you were going to say something like you raced a Gen1 or a Ferrari! LOL!

Auto Start/Stop issue?

^engine idling > hvac fan on high > auto start/stop wasn't a factor

As much as I dislike your trolling and arrogance, this really does suck. Sorry to hear that your new truck is having issues. Honestly, though, this is sometimes the risk of early delivery new launch vehicles. I hope Ford can find a cause and make sure it gets addressed for everyone else's trucks.
