If your experiencing lopey, erratic idle rpm there's a good chance your FPR or the FPR jumper harness is at fault. This FPR service kit from DHD is a favorite amongst installers. Our kit includes everything needed to do the job correctly, the first time. Each kit includes a new OE Bosch fuel pressure regulator, new hardware, new updated FPR/CP3 jumper harness and an application specific torx bit.
