Hello all, just recently purchased a used 06 lly bone stock, first diesel but not my first chevy by far. Had it about a month, a week ago I did egr delete and exhaust as shown in sig. Yesterday the truck went into limp mode and threw p0191 code for fuel rail pressure. I had already ordered a Bosch LBZ FPR, I've changed the fuel filter and cleared the codes. It cleared up the issue but I'm curious to know if the new FPR will remedy this issue or will t be returning to haunt me?

 

you should put this in the chevy section to see if someone can answere your question.
