1993 Nissan 300ZX Problems

Fuel 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.

Check PCV valves if vehicle emits blue smoke

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.

Ticking Noise When Cold Due to Broken Exhaust Manifold Studs

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.
