ENGINE TUNE-UP

Ignition timing

1. Warm up the engine to normal operating temperature.

2. Turn all electric loads OFF.

3. Connect the timing light to to No. 1 high-tension cord.

4. Check that the timing mark (white) on the crankshaft pulley and the timing mark on the timing belt cover are aligned.

Ignition timing : 8° ± 5°(BTDC)

It is not necessary to adjust the ignition timing.

Idle speed

1. Warm up the engine to normal operating temperature.

2. Turn all electrical loads OFF.

3. Connect a tachmeter to the diagnosis connector.

(O : RPM terminal)

4. Check that cooling fan dose not operate.

5. Check the idle speed.

Ignition timing : 800 ± 50rpm

The idle speed is controlled automatically by Engine Control Unit(ECU) turough the Idle Speed Control(ISC)
valve, it is not necessary to adjust the idle speed.

6. If not as specified, check the following items.

(1) Check diagnostic trouble code.

(2) Check vacuum in intake manifold while engine is idling.

Vacuum : more than 480mmHg

Check air leakage at intake air system component, if not below specificed.

(3) Check the installation condition of crank angle sensor

A. Clearance : 0.019~0.059in (0.5~1.5mm)
B. Check the alignment between crank angle sensor and target wheel.

Compression

If the engine exhibits low power, poor fuel econmy or poor idle check the following.

1. Ignition system.

2. Compression

193psi (1,333kpa, 13.6kg/cm²) - 300rpm

3. Fuel system

Inspection

1. Check that the battery is fully charged. Recharge of necessary.

2. Warm up the engine to normal operating temperature.

3. Turn it off for about 10 minutes to allow the exhaust manifold to cool.

4. Remove all spark plugs.

5. Disconnect the high-tension cords.

6. Connect a compression gauge to No. 1 spark plug hole.

7. Fully depress the accelerator pedal and crank the engine.

8. Record the maximum gauge reading.

Engine modle

TBD

Item

Compression

Standard

193psi (1,333kpa, 13.6kg/cm²) - 300rpm

Max. difference between cylinder

26psi (196kpa, 2.0kg/cm²)

9. Check each cylinder.

10. If the compression in one or more cylinder is low, pour a small amount of engine oil into the cylinder and recheck the

compression.

(1) If the compression increases, the piston, piston rings, or cylinder wall may be worn.

(2) If the compression stays low the valve may be stuck or seating improperly.

(3) If the compression in adjacent cylinder stays low the cylinder head gasket may be defective or the cylinder head

distorted.

11. Connect the high-tension cords.

12. Install the spark plugs.

Tightening torque : 11~17lb·ft (15~23N·m, 1.5~2.3kg-m)

REMOVAL

Engine

1. Relieve fuel system pressure.(Refer to Fuel system)

2. Disconnect negative battery cable(frist) and positive battery cable(second).

3. Drain engine coolant.

4. Remove data link connector upward from mass airflow sensor bracket.

5. Disconnect intake air temperature sensor connector and mass air flow sensor connector.

6. Disconnect air intake hose from throttle body.

7. Remove fresh air duct with two nuts.

8. Remove acceleratir cable and cruise control cable if equipped.

9. Remove air cleaner assembly with two bolts and one nut.

10. Disconnect brake vacuum hose from brake master vac.

11. Discommect purge control vacuum (PCV) hose from charcoal canister.

12. Remove upper radiator hose.

13. Remove heater hoses.

14. Disconnect fuel hose from injector rail.

KEEP OPEN FLAMES AND SPARKS AWAY FROM OPEN FUEL LINES OR A FIRE OR EXPLOSION MAY
RESULT.

15. Disconnect IAC and throttle position sensor TPS connectors.

16. Disconnect injector connectors.

17. Disconnect electric connectors remove bracket and reinstall engine hanger.

18. Disconnect engine ground strap.
