1.Before inspection, set vehicles. in the condition:
Engine coolant
lLights, electric cooling and
lTransaxle: Neutral (P
2. Connect the scan tool to the data link connector.
,
3. Attach a three-way joint to the vacuum
the fuel pressure regulator and the intake manifold, and
connect a vacuum gauge.
4.Start the engine and check that idle speed is withi n specifi-
cation.
Standard value: 800 100
5. Check the manifold vacuum.
Limit: min. 60

LASH CHECK
A tappet-like may be produced from several items.
Check the following items. 1. Engine oil level too high or too low.
This may cause, aerated oil to enter, the adjusters and
cause them to be spongy.
2.Insufficient running time after rebuilding the cyli nder head.
Low speed running up to 1 hour may be required.
3. Low oil pressure.
4. The oil restrictor pressed in to the vertical oi l passage
to the cylinder head is plugged with debris.
5.Air ingested in to oil due to broken or cracked oil pump
pick up.
6. Worn valve guide.
7. Faulty hydraulic lash adjuster. (1) Check for sponginess while still installed in e ngine.
Depress part of the cam follower just over the adju ster.
Normal adjusters should be free and very firm.
Spongy adjusters can be depressed to the bottomed
position easily.
(2) Remove a suspected hydraulic lash adjuster asse m-
bly.
(3) Clean out dirt and varnish with solvent.
(4) Reassemble with engine oil.
(5) Check for sponginess.
(6) If still spongy, replace
new adjuster
assembly. .
