Q: Hesitant start, rough idle on 1999 Lincoln Navigator

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
When I try to start the truck, I have to press down the gas to start. When it eventually starts, it idles rough like it wants to shut off. This just started happening after it got really cold. Can you help ?

You most likely have a Power Train Computer system problem with a fault code to help you diagnoses the issue.
This is the first place to start, check your codes and then go from there.
