Fuel Delivery and Air Induction: Adjustments

V6-229 & 231 Engines
The C3 system used on these engines, provide precise control of air/fuel mixture during all ranges of engine operation. Because of this system control, adjustment procedures must be followed in exact sequence to ensure correct mixture adjustment. Dwell readings from the Mixture Control (MC) solenoid are used for adjustment calibration. If unable to obtain specified readings, refer C3 System Section.
