I have been having some issues and ended up taking in to have the injectors replaced. The crankcase ended up with fuel in it. So we replaced the injectors actually a mechanic did and now we can't get it to run over 50 mph. He said all of the information when plugged in to the computer is good. Any advice?

 

Fuel rail pressure sensor bad or bypass/pressure regulator.

This is an '04.5 common rail motor, right?

 

Yes it is.

 

Could also be as simple as a plugged fuel filter or air filter.

 

Thanks keep them coming. We changed the fuel filter and it was running just fine before the injectors were replaced
