It about 5 degrees...

It about 5 degrees outside ,trk has 22,302 miles on it(2008 f350 lariet 4 door dually) hardly ever used in winter ,started blowing excessive exhaust smoke, intermittently appears to be bluish ,seems to happen after decelerating and then accelerating for a couple of miles ,and then clears up,nothing at idle and nothing at high idle ,no faults or regen lights on

Mechanic's Assistant: Have you checked the fuses? Have you checked the door switches?

Don't mean to be ignorant , but what how would doors effect exhaust?

2008

Mechanic's Assistant: Are you fixing your F350 yourself? What have you tried so far?

Hello, many people right now are having issues with their fuel filters plugging up with the colder temperatures/gelling. This can cause a lack of fuel delivery and intermittent drivability problems as you are describing. Make sure you fuel filters are clean, there is no water in the fuel concerns. A fuel additive may help this gelling issue. Make sure no diagnostic trouble codes are stored (even with the check engine light off). If there is any performance modifications like a tuner installed, you may want to cycle the settings to stock and back.

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.
