System OK
13
Measure the resistance of each fuel injector at 68
³
F
(20
³
C). The resistance will increase slightly at high-
er temperatures.
Is the fuel injector resistance within the value speci-
fied?
11.6–12.4
Ω

proper gap, burned electrodes, or heavy de-
posits.
3. Inspect the ignition wires for short conditions.
4. Inspect all of the ignition grounds for loose con-
nections.
