NOTE
If response time(s) is not 0.80 the following may be
causing intermittent failures:
a. sticky valve
b. air in fuel
c. low battery charge
d. broken spring or armature on the injector
e. problems in the charging system (loose
alternator belt, bad grounds, etc.)
f. signs of insulation wear on injector
harness
(1) Start and warm engine to operating temperature (at least 86 F).
(2) Plug in DDR and select INJ RESP TIMES (Mode 10).
NOTE
Table 2-5 gives the firing sequence in relation to the code
received.
(3) Read DDR display of injector response time (in firing order)
through several cycles. Note response time(s) of cylinder
by number in fault code.
Check which codes (61-68) are displayed by DDR.
