I might buy this truck in the near future... . The owner lives in Cali and bought this truck from the original owner. . He said it has after market injectors and fuel plate. . I was wondering if anyone recognized it could give me some info on it... . It is a 1998 12 valve 4x4 dually 5spd... I was also wondering how to tell if the KDP has been fixed and the 5th gear nut if it has been fixed... . Also how do I tell if it is a egr truck or not?? What are the disadvantages of having egr??
