[QUOTE="Macon, post: 1123786, member: 10768"] I would guess injectors are getting tired. Also, just because you are manually controlling the gpr (silly idea) that doesn't mean it's working properly. My gpr was working like a champ, but the contacts were so burnt that no power was going to the gp's. Hook an LED up to the gp side of the relay, mount it in the cab somewhere, and you'll always know when power is going to your plugs. [/QUOTE]
