3-16 FUEL SYSTEM (DFI) Throttle Control Cable
The throttle control cable is actually an assembly of three cables: the throttle cable, the throttle body cable, and the oil pump cableThe throttle cable runs from the throttle lever to the cable assembly junction where it connects to both the throttle body cable which leads to the throttle body, and the oil pump cable which leads to the oil pumpSince the throttle lever controls both the throttle body and the oil pump simultaneously, it is important that each cable be adjusted to its designed base position so that the oil and air mixture reach the engine in the correct proportion at all throttle openingsCable stretch creates excess play at the throttle lever and alters the base positions of the cables at the throttle body and the oil pump, necessitating periodic adjustment
Be sure to inspect and adjust the throttle body and oil pump cables at the same time
