1991 Nissan 300ZX ProblemsFuel Injectors May Fail and Cause Drivability Concerns
The fuel injectors can fail and cause drivability problems. Often there is no Check Engine light and the failures can be caused by corrosion of the connector, clogging beyond the point of cleaning, and/or internal failures.
If the vehicle fails the “State Smog Test” due to high emission readings, components in the pollution control system (air injection components) may have failed due to moisture and may need to be replaced.
If the car is emitting blue smoke from the tail pipe, from burned oil, be sure both PCV valves are functioning properly prior to replacing the turbocharger.
