13B-46
INSPECTION PROCEDURE 14
The feeling of impact when accelerating Probable cause
The cause is probably an ignition leak being generated in line with an increase
in the spark plug demand voltage during acceleration.
D Malfunction of the ignition system
NO
Check the following items in the order given.
D Ignition coil, spark plug
D Ignition leak.
MUT-
II
Self-Diag code
Is a diagnosis code displayed?
YES
Refer to P.13B-11, INSPECTION CHART FOR DIAGNOSIS
CODES.
INSPECTION PROCEDURE 15
The feeling of impact when decelerating Probable cause
The cause is probably insufficient intake air due to an idle speed control
malfunction.
D Malfunction of the idle speed control system
OK
Clean around the throttle valve. (Refer to P.13B-86.)
OK

CODES.
INSPECTION PROCEDURE 16
Knocking Probable cause
The cause is probably incorrect detonation control or an incorrect heating value
for the spark plugs.
D Malfunction of the detonation sensor
D Incorrect heat value of the spark plug
YES
Check the following items in the order given.
D Spark plug
D Contamination (water, kerosene, etc.) in the fuel
NO
Does knocking occur when driving while the detonation sensor
connector is disconnected? (At this time, use the MUT-II to check
whether the ignition timing is retarded from when the detonation
sensor connector is connected.)
NO
Check the idle speed control servo system. (Refer to P.13B-53,
INSPECTION PROCEDURE 26.)
