2012 GT feels like running on 4 cylinders

I just drove home from the grocery store and when I started my GT, the motor felt like it was misfiring immediately. It completely stalled at one point and after I restarted, everything went back to normal. A bad smell emitted from the exhaust after the stall. Anyone experience this before? I plan on brining it in to the dealership this week.

Mine did that while driving to Christmas midnight service. It then threw a CEL. The code which I don't remember said that there is a air/fuel issue when comparing left and right banks. Im not tuned and never was. Took it to the dealer and the tech ran tests for a couple hours. Nothing. He turned it off and it has not been back yet in 150 miles. He said that most probably its the additives that are added to the fuel in winter even when the gas is top notch sometimes cause a little glitch with the sensors, and that many of the sensors in the motor act up during cold weather.

Mine cold starts normal. But warm starts it ALWAYS does that for a few seconds. I have to rev it a little to get it to smooth out. Dealer says this is a normal charactersitic. It's annoying and aggravating. And, as you pointed out, it smells like a bad catalytic converter.

Hello Wolff,

Welcome to the forum! My name is Deysha with Ford Service, and I still recommend you bring your vehicles in to your Ford dealers for diagnosis. Then, PM me with your VIN, dealer, mileage, full name, and best daytime number so I can escalate this to the customer service manager for your area.
