an O-ring which seals the pipe and quick connector
that can be contaminated.

2. INSPECT FUEL CUT OFF RPM
(a) Check the operation.
(1) Increase the engine speed to at least 3,500 rpm.
(2) Use a sound scope to check the fuel injector operating noise.
(3) Check that when the throttle lever is released, the fuel injector operation noise stops momentarily
at 2,500 rpm and then resumes at 1,200 rpm.
2,500 rpm: Fuel cut off rpm
1,200 rpm: Fuel return rpm
3. VISUALLY INSPECT HOSES, CONNECTIONS AND
GASKETS
(a) Check the appearance.
(1) Check the engine assembly to see if the indicated
portions by the arrows have cracks, leaks or dam-
age.
HINT:
Separation of the engine oil level gauge, oil filler cap, PCV
hose, etc. may cause the engine to run improperly. Disconnec-
tion, looseness or cracks in the parts of the air induction system
between the throttle body and cylinder head will allow air suc-
tion and cause the engine to run improperly.
If necessary, repair the engine assembly.
4. INSPECT EVAP SYSTEM LINE
(a) Warm up the engine to the normal operating temperature.
(b) Connect the vacuum gauge (EVAP control system test
equipment vacuum gauge) to the EVAP service port on
the purge line. Then stop the engine.
(c) If you have the hand-held tester:
Force the VSV for EVAP to operate.
(1) Connect the hand-held tester to the DLC3.
(2) Start the engine.
(3) Turn the hand-held tester ON.
(4) Use the ACTIVE TEST mode on the hand-held tes-
ter to operate the VSV for EVAP.
