I have a 2004 ford f250 6.0 powerstroke and when you drive

Customer Question

I have a 2004 ford f250 6.0 powerstroke and when you drive for a while you loose power and the exhust will start to sound like a restricted exhaust and you eobt be able to go past 30-40 mph. If you turn the key off and restart it's fine till you drive
for a while again. I scanned for codes and they are as follows : P132B-60 - turbocharcher/ supercharger boost control A performance, P0263-60 cyl. #1 contribution/balance & p0275-60 cyl#5 contribution/balance

My name is ***** ***** I will assist you.

Are you getting heavy smoking when this occurs? Does it smell like unburned fuel?

Have you tried cleaning the exhaust back pressure tube?

Haven't noticed any heavy smoking and I don't smell unburned fuel and I have not tried cleaning the ebp tube.
Expert:  Jeremy replied 1 year ago.

Try cleaning the EBP tube first since you are getting the turbo codes. It is what senses the pressure coming from the turbo and makes the adjustments for it. It can also create a contribution imbalance code.

If that doesn;t resolve the issue, then you may have 2 separate issues going on. One being an issue with the injectors and the other being on the intake, in particular the turbo. If we have to go to the next step, I would pull the turbo and crack it open, then clean it. I can provide the info to do that if needed. That will clean up the vanes on the turbo and should hopefully get rid of the intake problem.

Next will be to see why the injectors are giving a bad contribution test by pulling them and testing them. I prefer to start with the items that can cause both issues as well as the simplest.

not the website. I have no control over the site fees, site errors, category errors, or how long it took for a response for these reasons.

I am not an employee of this website, so please rate with a POSITIVE (green) rating for me to get credit for assisting you. You still pay

I want you pleased with my service to you so please inform me before rating negative (red) and I will do my best to make it right. Follow

I do have many workshop manuals, diagrams, etc that I pay to get access to out of my pocket. If one is needed, please ask and I will give
you an offer at my technician discounted cost to you for such manuals. I never charge above that cost.

If all goes well when I arrive at the shop, around 8-9 AM. If there is a disaster, it is usually around 11 AM. I try to check the board by then each day.
