Good afternoon, I hope you doing great today! My name is***** am a Ford master technician and would be happy to assist you with this today.

Does the truck have a check engine light illuminated? If so, we will need to get the codes read. If no check engine light then we will have to do a few manual inspections.

First thing that needs to be inspected is the EGR valve. The 6.0 engine is notorious for plugging the EGR valve, when this happens you will see a lot of black smoke until the throttle is almost wide open

no light on

Ok, then we will not worry about that.

I would start by removing and inspecting/cleaning the EGR valve, we need to make sure it is moving freely and not plugged up

What Customers are Saying:

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.

MollyUSA

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
