Nissan Maxima: 1982 Maxima fuel problem

hmmmm , here we go again gang.


What could it be ??

A rich running condition ?

What are the signs of an overly rich mixture condition besides poor gas
mileage ?


Remember this is an old 810 series maxima with the L24 engine (in line 6
cylinder)

> What could it be ?? 

Bad O2 sensor(s)
Bad fuel injector(s)
Overcooling engine (i.e., thermostat stuck open during cooler weather).

I'm not familar with the L24 engine... but here goes:

Signs of an overly rich mixture:

1) Carbon fouled spark plugs (electrode and tip)
2) Smell of raw fuel in the exhaust (possible black/grey smoke from exhaust?)
3) Possible long-term side effect includes a plugged catalytic converter

Possible causes:

1) O2 sensors
2) Bad Engine Coolant Temperature Sensor
3) As already suggested - stuck open thermostat - car always running "cool"...
4) Leaky injectors

Nirav wins , Good answers man.( you wouldn't be looking for a technicians
job would you ? ;- )) )

Keep up the good work

The answer to this cars running conditions lies within Nirav's post.

He has their signs and their possible causes listed, one of them is the
answer, it is now up to the owner to do a little diagnosis and figure out
what may be causing it .

Actually the most likely problem is an air flow meter issue on one of those
models.
