Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Electronic Spark Control System: Description: Notes
The Electronic Spark Control (ESC) system is governed by a Spark Control Computer, 7 engine sensors, a specially-calibrated carburetor and, on most models, a dual pick-up distributor. V8 models with electronic fuel injection (318" EFI) have a single pick-up distributor. The ESC system is designed to burn a lean air/fuel mixture, with a minimum of emissions. See Figure.
