Idle Speed Control
The ECM varies the timing and the fuel flow based on the throttle opening to maintain an
idle speed of 650 rpm ± 50 rpm.
RPM-Limit Circuit
The rpm limit circuitry is contained within the ECM. When the rpm limit point is reached
(this point will vary between engine models), a warning horn will sound. If the rpm contin-
ues to increase, ignition spark will be cut to cylinders #1, #3 and #5. If the rpm still contin-
ues to rise, fuel and ignition spark will be cut to all cylinders.
