Need to press brake pedal to the floor sometimes in order to get truck out of park

Already put new multifunction switch in and still have same problem.

This vehicle will start and run flawlessly for the most part. It has begun to start and run for a split second then shut off. After 15 - 20 tries it will start and run like there was never an issue. It makes no difference if the engine is hot or cold. Previous experience tells me that it could be a coil. Codes were read and two showed up. 1) misfire #6, 2)emissions below average. This has happened for the last three weeks; once a week.

the service 4wd comes on but it still works cut the truck on an off service 4wd is gone

when I restart the truck the 4wd doesn't show up

Miles my car didn't want to pull forward and started smoking what's wrong
