Misfire
Bought a 2014 mustang gt 4 weeks ago. Driving home from work 3 weeks ago and a flashing cel came on. Didn't actually notice any misfire. Took it to the dealer, and they did a relearn. A couple weeks without an issue, so I decided to put on a intake, exhaust, and tune. 2 nights ago, driving home from work, get a flashing cel again. This was after I downshifted and passed a couple cars. When I noticed the cel I gave it some gas to see if I could notice a misfire. This time I noticed a misfire. I've read that the u2 sensors are kinda sensitive, could it have been because the car wasn't up to full operating temp? Any suggestions would be great so I have something for the dealer to look into. Wanna get this resolved as soon as possible so I can continue to mod this beast, without having to go backwards
lol. Thanks ahead of time.

lol. Thanks ahead of time.Welcome to the forum! My name is Deysha with Ford Service and I recommend you bring your vehicle in to your Ford dealer for diagnosis again. 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.
