Description

Engine Hesitation is caused by inaccurate engine timing, abnormal fuel or faulty sensor & actuator. The purpose of the "Basic Inspection" is to check engine timing, fuel condition and sensor & actuator.

Diagnostic Procedure
Engine timing Inspection
1.

Set the TDC mark on the crankshaft pulley with the "T" pointer.

2.

Set the camshaft sprocket to TDC by aligning the TDC marks on the camshaft sprocket with the pointers on the cylinder head. Dowel must be upper side.

3.

Are TDC marks on the Pointers?

YES

Go to "fuel inspection" procedure.

NO

Repair or Replace the timing belt.

Fuel Condition
4.

IG "OFF"

5.

Remove the fuel pump and inspect the fuel condition.

6.

Is the fuel normal?

YES

Go to "Sensor and actuator inspection" procedure.

NO

Replace the fuel.

caution

■ Characteristic of abnormal gasoline

1) Toxic odor

2) Eyes stung

3) Hard vaporizing

4) Knocking suddenly after fuelling up

5) Hard starting after fuelling up(In the winter)

■ Influence of abnormal gasoline

1) Knocking

2) Excessive fuel consumption

3) Poor power/acceleration

4) Fuel system damage such as fuel pump, Injector and component of the combustion-camber damage (pistion etc...)

5) Deposit rising or corrosion (in the engine and fuel system)

6) Fuel pressure decrease or Engine stalling by vapor lock.

7) Impossible starting by low volatile

8) Discharge carcinogen

9) Discharge pollutant(CO, HC, NOx etc...)
