conds, and measure the injection volume with a gra-
duated cylinder. Test each injector 2 or 3 times.
SST 09842-30060
Injection volume:
111 - 141 cm
3 (6.8 - 8.6 cu in.) per 15 sec.
Difference between each injector:
10 cm
3 (0.6 cu in.) or less
If the injection volume is not as specified, replace the injector.
2. INSPECT LEAKAGE
(a) In the condition above, disconnect the tester probes of
SST (wire) from the battery and check the fuel leakage
from the injector.

THROTTLE BODY
ON-VEHICLE INSPECTION
1. INSPECT THROTTLE BODY
(a) Check that the throttle linkage moves smoothly.
(b) Check the vacuum at the purge port.
Start the engine.
Check the vacuum with your finger.
Port nameAt idleAt 3,000 rpm
PurgeNo vacuumVacuum
2. INSPECT DASHPOT
(a) Warm up engine.
Allow the engine to warm up to normal operating tempera-
ture.
(b) Check idle speed.
Idle speed (Transmission in neutral position):
650 ± 50 rpm
(c) Check and adjust dashpot setting speed.
(1) Disconnect the control cables from the throttle
body.
(2) Turn the throttle linkage until the dashpot adjusting
screw starts to separate from the push rod. Then
keep the throttle linkage at that position.
(3) Check that the dashpot is set.
