What’s going on y’all, I bought this 2014 mustang GT about 2 weeks ago. Been having some fun driving this very loud baby around! Well when it’s not throwing codes. It’s happened twice after I got it home. I got a P0100, P1299 and P0100 again in that order.
P0100 (Mass or volume air flow a circuit)

P1299 (cylinder head overtemp protection active)

When the P1299 code comes on the car goes into protection mode, idles very rough and dies out if I try to drive it. Also the engine was not over...
