My 92 Maxima, V6, VG30 is having serious flooding problem. The local repair shop do not know the cause.
I have checked with NISSAN Consult tester. There is no code. Checked the Engine TEMP sensor, MASS AIR FLOW sensor, AAC VALVE.
Fuel injectors are also ok.

Symptoms: Idle rpm is not steady. Engine is hunting and many times engine will quit during the idle condition.

Pickup is also not how it used to be. The fuel consumption is way beyond the normal condition(100Miles/15Gallon)

Any help on this area will be greatly appreciated!

Thanks,

 

Fuel pressure regulator?

 

maybe fuel pump also?? I replaced mine today...my idle which as of late was between 500-600RPM shot back up to the usual 700-900rpm and the "truck-like" noise died down...check your fuel pump too!
