- Connect a tachometer to engine. Start and run engine until it reaches normal operating temperature. Depress accelerator, then release accelerator pedal. Engine speed should not immediately return immediately to idle. On vehicles equipped with A/C or heated rear window (EBL - electrically heated backlight), a slight increase in idle speed should be observed while A/C or EBL are turned on.
- Turning off either device will return idle speed to normal. As the A/C clutch cycles on and off, the throttle kicker solenoid (solekicker) plunger should extend and retract. If plunger does not move with clutch cycling, or after engine starts, or when the EBL is turned on, check the kicker system for vacuum leaks. If engine speed does not increase as specified, disconnect the 3-way connector at carburetor.
- Connect ohmmeter leads from ground to solenoid terminal that was connected to black wire. Resistance should be 20-100 ohms. If not, replace solenoid. Reconnect solenoid. Start vehicle and immediately (before 2 second time delay times out) measure voltage across vacuum solenoid terminals.
- Voltage should be within 2 volts of charging system voltage. If not, replace computer. Turn on A/C or EBL after time delay has timed out. Charging voltage should once again be present at solenoid.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
