2014 EcoBoost Limp Mode
2014 F-150 EcoBoost with 155k miles, never had a problem before like this before, but the past couple days it had gone into limp mode twice. The first time was first thing in the morning getting on the highway, so heavy acceleration, second time was just driving down the highway at full speed. I had a check engine light come on the day before but didn't check it right away. After the first time going limp mode, I hooked up a reader and I got a Oxygen sensor 1 circuit low. I've read about a lot of EcoBoost having this problem and it being the throttle body, and some spark plugs just needing replaced. Has anyone had this issue with O2 sensor causing a misfire and going to limp mode? One thing to note is there has been extremely cold temps here in MO, which could be factoring into it. Thanks for any insight/advice!
Clean the MAP sensors.

I've had all four 02 sensors replaced but none of them caused the truck to run that poorly however, two of them did throw a code and I replaced the other two to avoid imminent failure.
The plugs and boots on these trucks are historically good for about 50K-60K miles. Some better, some worse.
