Default Hesitation on start with 2001 Maxima - 08-26-2006 , 11:01 AM






Whenever I start my 2001 Maxima in the morning it has extreme
hesitation for about 10 seconds and then seems to run normally. The
service engine light also came on recently and it is P0171 (System Too
Lean (Bank 1)). I tried putting in a bottle of fuel cleaner, but it
doesn't seem to have helped. I live in Arizona and so it's not that the
engine is just too cold or anything, so does anyone have any ideas on
what the problem could be?
Thanks,
Dave

When's the last time you had your throttle body cleaned?

I bought the car about 2 1/2 years ago and I've never had it done.
Where can I get it done or is it something that I could do myself?
Thanks,
Dave

Dealer can do it,,about $200 bucks,,,,

Its not something you want to fool around with yourself, you could
damage the MAF.

You need to stop pretending to be a mechanic.

Screw up that filament in the MAF sensor, and you bought yourself a
500 part, and a tow trunk to the dealer.

or do you even know how a MAF sensor is made, or works,,,????

You need to stick with being a chemical engineer. It is a very easy
job to clean the throttle body. What you said is analogous to saying
keep the doors closed so you don't get a ding.

You can easily do it yourself. Remove the air filter, the air filter
box and the tubing that goes to the engine. Once you've reached this
cylindrical metal part with a butterfly valve in it, that's the throttle
body. To verify, have someone push the accelerator pedal, you will see
the butterfly valve move. The TB is probably black with all carbon
deposits gunk from years of use. No biggie. Get some throttle body
cleaner (NOT CARBEURATOR CLEANER) and spray and wipe profusely, clearing
out all the gunk until you see shiny metal. If you really really want to
do a good job of cleaning it, you can take apart the throttle body to
clean the back end of it as well, but it isn't absolutely necessary.

When I did this on my 98 Maxima, and I only did the front part of the
TB, my cold start idle jumped from 1200 rpms to 2000. Also, my lower
rpms drivability was much improved. I did my TB cleaning after 140K
miles of use which was a loooong time

And all you ever post is -

"No that's wrong - because I think its wrong"

No data, no facts, no anything,,just "you think its not so,,,"

Dude you lost all credibility on this group when you stated that its
Ok to run a Maxima on Reg Gas, and if you blew the engine doing so
that was OK to since it would be covered by the warrantee.

This is a 30K plus car,,its not your Daddies 67 Dodge Dart,,,,

Check all the post on this group,,,90 percent end up having to take
the car to the dealer to get fixed,,,,thats a reality of modern
cars,,,not some psycho personal opinion of yours.

and claiming your a "mechanic" justifies nothing - most post on this
group are complaints about incompetent mechanics.

Yes, I do and have actually had some off. Just don't drop anything in
the tube and there will be no problems. The filament isn't hanging out
in open space. Maybe you are just exceptionally clumsy and have to
worry about such things. Most wouldn't. Maybe you have an interest in
a dealership or something. Your usual reply for most faults is to take
it to the dealer. Can you check your own air pressure? Do you?

Have you noticed that every other reply has told the OP that it is no
big deal?

I cleaned out the throttle body on Saturday (it was pretty dirty and
definitely needed it) and cleared the code, but it still has the
hesitation problem on the first start in the morning and the check
engine light came back on today. The code is P0171 (System Too Lean
(Bank 1)). Does anyone have any ideas on what the problem might be?
Thanks,
Dave

Your check engine code will be back - in 3 engine cycles or so.

Like I tried to tell "you know who" the psuedo mechanic. Glad you
didnt make things worse by following his idiotic 'shade tree mechanic"
advise.

Your problem is most likely not a dirty anything - its most likely the
MAF, or a bad fuel injector.

Of course 'you know who" is going to tell you to spray more gum out on
it,,LOL i am going to risk being flamed (god bless that ignore
function,,LOL), and tell you you need to go to a Dealer.

i am in Az to,,use Midway, though less than impressed lately with
them. Friend of mine goes to one in Peoria - has been very happy with
them.

Would be glad to ask him and send you the info.

No its not going to be cheap - but you will get your car fixed, and
fixed the first time. Sorry, hate me for the truth if you want, these
are complex/expensive cars to fix.

Oh and BTW - i own a 2000 Maxima,,,what does "you know who own"....a
67 dodge dart,,??..LOL

Of course he is going to call me an idiot for telling you the truth,,,

Hey so be it..LOL Gives me a chuckle everytime I think about it,,LOL

Hope you get your car fixed,,,
