Hi all,
I hope someone can help me. About a year ago my 2000 maxima began to
stall intermittantly after the engine warmed up at idle. No check engine
light ever came on. I took it to the dealer and they fiddled around with
it and found nothing even though it stalled for them a couple of times.
Additionally, when they gave my car back to me the electronics that
control the door locks and a few other things was mysteriously broken.
They refused to take responsibility and fearing more 500 dollar errors, I
took it elsewhere. The new mechanic never did discover the underlying
problem. I gave it some fuel injector cleaner and the problem went away.
Almost a year later, the problem has returned, and this time the fuel
injector cleaner didn't work. Here's the information I've been able to
gather.
The car stalls at idle, usually when in drive or reverse as I come to a
stop at a stoplight or change gears to back out of somewhere.
It seems to do it more often when it has less than a half tank of gas.
It occasionally stalls in park, but usually only after it has already
stalled once.
I was reading the posts about the 97 maxima that was doing the same thing,
but this Niss Tech never gave a verdict.
I'm afraid to take my car back to the dealer because they'll probably
break some other $500 thing that I have to pay to fix. I'm on the verge
of making a desperate plea to the car talk guys.
Any thoughts?

You're probably not going to find the answer here. It needs some
troubleshooting by someone that knows what he's doing (and can see/touch
the car).

use the connected links for your help on this. it sounds like the knock
sensor could be bad or is gong bad. I had this problem on a 95 maxima, but
you have the same symptoms and after researching the net, they say the same
about the 2000 maxima also.

Thanks for the posts, and I'm interested in other suggestions as well.
Right now I'm compiling a list of possibilities to take to the mechanic.
Jesterwoo, do you remember what your search criteria was when you searched
for this problem? When I initially did my search I typed in Maxima Stalls
on google.

I have similar problem with 1984 Maxima - stalls when engine reaches
operating temperatures and idling in stop and go traffic. Could it
possibly be the oil pump? Noted that for the first time in 20 years there
was some seepage from the rear main bearing so I used an oil treatment in
the last oil change Oil pressure on cold starting is around 4 kg/cm2 = (57
psig) but drops to about 1.5 kg/cm2 (<21 psig) when the engine is warm and
ambient temperature is above 70F. Winter in Calgary has eliminated the
stalling problem, because the maximum temperature in the past month has
been 40F.

My 2000 Max has been doing this like clockwork since it first hit about
45K. The culprit in my case has been the Throttle Body. It requires a
really good cleaning to keep the Idle Air passing through when you release
the accelerator. Remember, when your car is not fully warm, the TB is
opened slightly, but once it is warm, it closes completely when you step
off of the Gas Pedal. The ECM is in control to slightly open the TB when
this occours, and over time, the TB gets build up, and this slicht amount
of oppening is not sufficient to keep the idle up, and the engine stalls.
I reccommend that the TB be cleaned every 30 - 50k to keep things running.
Also, make sure you are using an O2 sensor safe cleaner (Very Important).

That problem was in my friends car... after several trips to the
dealer, the dealer basically gave up as did another independent
mechanic. I finally decided to go with my gut feeling of a bad MAF
(as Steve T had originally suggested in that thread) and bingo,
problem fixed. The MAF never posted a CEL and sometimes the car would
run fine for weeks on end and then all of a sudden, it would stall 3
times in an hour. As Steve stated in his original reply, sometimes
the only way to test if its a MAF or not is to replace it with a known
working MAF and see if the problem goes away.

Thanks for all the great suggestions. It's at the mechanic now, with a
list of my primary suspects. I'll let you know what the verdict is,
hopefully later today!!

i think i am having very related problem - same situations - but not
everytime - when idling, going slow (<10mph), the engine kind of makes
this noise - rattling noise - basically it stutters. But at higher
speeds it runs just fine. And y'day at the end of stuttering, the
'Service Engine Soon' Light came on :( today morning everything was okay
but the light is still on.

i will need to take my car to the dealer this weekend or later to get it
checked out. do, keep us posted on your progress.

thanks,
+ravi

The mechanic cleaned the Throttle Chamber and now the car seems to be
running fine!
Thanks EVERYONE!!
Hopefully this will really be the end of it!

great that your car is fixed :) !!

i have a question - you meant the engine stalls - does that mean the
engine comes to a complete stop ? pardon me - i am a novice :(

btw, i noticed the idling Engine RPM is around 700. Is that normal ?

i will be going to the dealership this weekend (last weekend, i couldn't).

thanks,
ravi

Had one at my shop crank ran and stall when up to temp. After testing and
checking throttle body for being dirty it ended up being the temp sensor . The
test is when it does start to stall when warm unplug the temp sensor see if it
will crank then, hope this helps
