I have a 1999 Ford Super Duty 7.3 w/ Turbo. I noticed that the engine is starting to run rough and starting to loss power. The oil and temp. are running fine. How can you tell if the turbo is working or not. Can someone please help me fine the problem. There is no smoke. I did have to have the number one injector replaced about 3months ago. PLEASE HELP

 

check uvch's maybe time for new fuel filter? just two of the easier things it could be maybe

 

When's the last time you changed the oil??

 

The fuel filter,air filter and oil was changed on June 2,2010 Can you tell me want UVCH means.

 

It's the harness under the valve cover. It stands for Under Valve Cover Harness. But I don't think it's your UVCH. Do me a favor. Unplug your injection control pressure sensor.



Let me know how your truck runs. Also, how much oil is on the plug.

 

Can you tell me were the ICP is located.

 

On my truck with loss of power. I took the truck on a trip this weekend with the LQ horse trailer. I ran fine on flat road. But going up grades in Neveda the turbo would work only part of the time Can someone PLEASE help me with this problem on the turbo why it would only work sometimes.

 

im waiting for the outcome

 

I unplug the icp and it did not make a diffence there is very little oil on it

 

Again, when was the last time you had a oil change? It could be dirty oil or even be low on oil.
