FUEL INJECTORS

1995 Nissan Maxima • 6 cylinder 2WD Automatic • 132,000 miles

I have a 1995 Nissan maxima, and overall, the engine is running roughly. I'm thinking injector since the plugs and coils are good. I have replaced the front injectors when they go bad, but to replace the rear ones, it seems very time consuming. Is there a way to check the rear fuel injectors (screwdriver test) without removing the upper intake manifold?

1.Defective spark plugs
2.Inadequate spark/coil,defective spark plug wire.
3.Lack of compression
4.False air leakage.
5.Faulty fuel injectors.
6.Insufficient fuel pressure.
7.Contaminated fuel.
8.EGR valve that is leaking.
9.Oxygen sensors.
10.Throttle position sensor.
11.Manifold absolute pressure sensor
12.Mass Airflow Sensor
13.Idle air control valve

Note: If it doesn't apply disregard it-
