Description

Poor power/acceleration could be caused by inaccurate engine timing and fuel condition. Go to sensor & actuator Inspection after checking engine timing and fuel condition.

Diagnostic Procedure
Engine timing Inspection
1.

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

2.

Set the timing marks on the camshaft sprockets(Left,Right) with the pointers of the cylinder head covers(Left,Right).

3.

Are TDC marks on the Pointers?

YES

Go to "fuel condition inspection" procedure as below.

NO

Repair or Replace the timing belt.

Fuel condition Inspection
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 in the basic 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...)
