HINT:
As a large amount of exhaust gas enters, the engine will misfire
slightly.
(g) Remove the vacuum gauge, and reconnect the vacuum
hoses to the proper locations.
(h) Inspect the EGR valve.
(1) Apply vacuum directly to the EGR valve with the en-
gine idling.
(2) Check that the engine runs rough or dies.
(3) Reconnect the vacuum hoses to the proper loca-
tions.
HINT:
As exhaust gas is increasingly recirculated, the engine will start
to misfire.
(i) Remove the SST from the DLC1.
SST 09843±18020
2. INSPECT EGR VACUUM MODULATOR
(a) Disconnect the vacuum hoses from ports P, Q and R of
the EGR vacuum modulator.
(b) Block ports P and R with your finger.
(c) Blow air into port Q, and check that the air passes through
to the air filter side freely.
(d) Start the engine, and maintain speed at 2,500 rpm.
(e) Repeat the above test. Check that there is a strong resis-
tance to air flow.
(f) Reconnect the vacuum hoses to the proper locations.
