93 GXE -- Lumpy Idle/Faulty fuel gauge
Lumpy idle:
Idle lumps sporadically when engine is cold or warm. Feels like it wants to die once its warmed up. However, it runs smooth once your driving. The lumply idle only seems to occur when stopped and foot is off the gas pedal.
Fualty fuel gauge:
Appeartly when the fuel level reaches half a tank, the guage needle drops below E. It reads fine at any level above half.
Any suggestions (this is for my bro's '93 GXE)?
Thanks in advance.

Similar problem - rough idle
Hi,
I have a rough idle in my 93 maxima GXE, with 120 K miles on it. the car idles rough only in Drive or Reverse. As soon as I change to Park or Neutral, it becomes smooth again. When in motion, i.e. when the accelerator is pressed even a little bit, the roughness goes away. The rpm when the car is cold is >1000 both in Drive and Neutral. Its not rough then. When its heated up nicely, the Drive idle rpm is 600 and Neutral idle rpm is 700.
I had 2 injectors replaced last August, and the engine does not miss at all. The pickup is what you'd expect from a nissan v-6, albeit slightly on the slower side due to the heavy mileage on the car. I use an injector cleaner every 4-5K miles. I had a tune-up last August when the spark plugs were replaced, but probably not the wires.
A mechanic told me yesterday, that the idle rpm in Drive and Reverse is too low, that it should be slightly higher, and that if it were, the car would be smooth when idling.
Can you give me your rpms at idle, in Drive, when engine is cold, and then when hot?
