Help Needed 6.0l hesitation & vibration

[brocktoones]

Having major problem with driving on highway. First time owner and operator of a diesel truck. At speeds of 100km/h - 120km/h with throttle just tipping in and RPM's at or about 1000-1300rpm the vehicle starts to hesitate, bucks and vibrates causing entire vehicle to shake. As soon as I step into the throttle and turbo really kicks the problem mostly stops. Only seems to happen on the highway. Tried new tank of diesel, new fuel filters, added cetane and performance booster and added new air filter. Nothing has worked. Checked for codes and none were present and no engine check light on as of yet. Any ideas or help will be great.

thanks.

Sounds like an EGR problem. Usually you will get a code. You will need to have the EGR cleaned, or do it yourself. Common problem with 6.0 engines. Fill out your signature by going to the USER CP in the Blue line above. This will help us help you.

Dave,

How do you clean it?

Barrett, I found an article at Ford Doctors site about cleaning the EGR.

Diesel Technician Society It is pretty easy and is a good article. Have fun...
