Examination
1. Idle speed is the engine speed when the gas pedal is released. This parameter is one of the critical ones, determining both the operation of the engine as a whole and the proper functioning of its various subsystems.
2. Set the parking brake and chock the wheels. Make sure the transmission is in neutral (manual transmission) or in position "P" or "N" (automatic transmission).
3. Connect a hand-held tachometer according to the manufacturer's instructions.
4. Disconnect the 2-pin electrical connector from the EVAP canister purge solenoid valve (see accompanying illustration).
5. Start the engine and warm it up to normal operating temperature at 3000 rpm.
6. Once the cooling fan starts, slowly reduce engine speed to idle. Make sure all accessories are off and the transmission is in neutral (manual transmission) or in the "P"/"N" position (automatic transmission).
7. Read the tachometer reading and compare it to the value given on the VECI label or in the Specifications for this Chapter.
Note: In case of discrepancies, the information provided on the VECI label shall prevail.
Adjustment
1. Before starting adjustments, make sure that the cooling system fan is turned off.
2. If the idle speed is outside the permissible range, remove the plug (see accompanying illustration) and make the necessary adjustments by turning the adjusting screw with a screwdriver in the appropriate direction. Turn the screw in short steps (1/4 turn per approach), checking the new engine speed each time.
3. Stop the engine and disconnect the tachometer. Restore the original connection to the EVAP solenoid valve.
