Powerstroke dying when cold. Fine after letting it warm up
I have a 01 F-350 Powerstroke with 140,000 miles. Pretty much all stock except a 6 position TS chip that i normally run on the 75 hp gain setting. I started having a problem that in the mornings when you first go to drive it that it will get about 1/4 mile and then it will die. It starts losing power and it blows a lot of white smoke and then eventually it will die. Then its really hard to start back up. It does this more on colder mornings but it doesnt have to be very cold to do this. If you let it warm up for about 10 minutes then it does fine and won't die. All Ive tried so far was to change the fuel filter. Thoughts?
