Battery and Electrical Systems TPS Idle Speed AdjustmentCFI Models
12Verify the TPS voltage is 0.70 +- 0.01 Vdc with the throttle plates closedSlowly turn the idle speed adjustment screw (A) clockwise until the voltage displayed on the multi meter reads 0.95 +0.1 Vdc (.93 +- 0.1 Vdc for 800 CFI engines)Carefully tighten the lock nut (B) while maintaining the voltage settingSynchronization ScrewThrottle Arm TabScrew Mount 4Slowly turn the synchronization screw inwards until the instant the voltage on the multimeter changesBack the screw out so the voltage reads 0.70 +- 0.01 VdcNOTE: When turning the synchronization screw, do not push the screwdriver with enough force to move the throttle cable camDoing so will affect the TPS voltage reading on the multimeterReinstall the throttle cable, then install the throttle body back on to the engine
