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.

Nissan 300ZX Problems
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.
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.

Nissan 300ZX Reviews

Chamorro Action, Adios
I purchased a 1990 TT many years back and had electrical problems where the car just would not start, Nissan could not figure it out. Then the automatic transmission when out. Got rid off the car and lost money on it.
I have always liked these cars and heard good things about other later models, so I did regret buying the 1990 model.
Just recently after several years I purchased another one, could not stay away from these Z ! This one is a 1995 non-turbo with 5 speed transmission and had 95k miles. Well so far, all is good ! Smooth transmission and strong engine ! I am really enjoying this car and glad I finally am enjoying one of these great sports cars.
in terms of overall peformance its the best car for the money
Stock 1995 AT nissan 300zx NA. With the miles up to 194K the car is still in great running condition. A/C still very cold, transmission shift smooth. Alternator died around 190K.(From 190K) I replaced NGK spark plug, fuel filter, K&N air filter and Brake pads.Next on the list is to Replace and refill: Radiator coolant, Differential and AT transmission (fluids).
This car is fast, fun, and hot!
