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.
Ignition Timing
Ignition timing is computer controlled and is not adjustable. Standard reference timing data for various engine operating conditions is stored in Engine Control Module (ECM) memory. ECM controls ignition timing based on engine operating conditions (speed, load, temperature, etc.) and data stored in ECM memory. ECM controls timing through ignition coil operation. When inspecting ignition timing, ensure it is as specified. See IGNITION TIMING SPECIFICATIONS table.
