truck just threw this code runs like crap when you trying to go but when your cruising at 2000 it sounds normal just no power i know it has to do with the rail pressure does that mean the sensor is shot and when it goes bad does it more than likely pop the safety plug in the rail thanks chad


also it sounds like crap to i guess it would be injector rattle and surges and blows both black smoke and white and its not the injectors cause they would do it all the time

 

Per MADDS Electronics:
Fuel rail pressure sensor voltage too low

 

FWIW, Shortly after I got my 05, I got a P0191 code.
Went to the dealer and they replaced the sensor.
Iv had it once since the sensor was replaced and they cleared trhe code with no ill effects.
Iv heard of several 05's getting this code.
Also heard of a couple of newer ones getting it as well.
