Diagnostic Aids

Check for faulty fuel injector. Check for partially blocked fuel injector nozzle. Check fuel injector resistance. Resistance should be 0.5-1.5 ohms at 68°F (20°C). Resistance of fuel injector resistor should be 1.9-2.8 ohms at 68°F (20°C).

An intermittent condition may be caused by a poor connection, rubbed-through insulation, or a broken wire inside insulation. Check PCM harness connectors for backed-out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal-to-wire connections before replacing component.
