Hi guys, Im having a problem with my 'new to me' 6.7 cummins. This is my first diesel but im learing fast!
The truck has straight pipe, smartyME, deletes.
The problem Im having is when I drive down the highway it throws code p000f, fuel valve opened. That is the ONLY code. When driving I can tell when it happens because the truck is down on power making almost no boost, BUT it does not 'fall on its face' like it should if its really blowing off 30k lbs of pressure!
The werid thing is its only going down the highway after about 30min. I can drive it wide open stop light to stop light and its fine!!
Any ideas? I dont think the valve is really open, mabey a bad sensor? something wrond with the cp3?
(i have this post on other sites as well so if this is old to you then I appologize, thanks for the help)
