1991 Nissan 300ZX Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 1991 Nissan 300ZX

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.

The exhaust manifold often warps, breaking off the studs between the cylinder head and the exhaust manifold. The noise may be most noticeable when the engine is cold.

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.
