alrite i was drivin home, when i down shifted into third goin about 60mph, all of the sudden my car loses power and starts stutterin. then the car shuts off!!! goin 50ish. i pull over and try to start but it would start up then shut off. after an hour of tryin to start the car i started the car up but pumped the clutch and it stayed idle. but when i drove off the car wouldnt go past 2000rpm in ne gear. also stutters in 3rd gear and the check engine light is on too. what can be the problem???!!!!!
PLEASE HELP ME!!! i have a 2000 se with 28000miles...is it still under warrentee?? is my car in safe mode??? should i reset ecu???

 

I don't have any specific suggestions, however, it certainly does sound like you have some form of ECU problem. Not being able to go over 2K RPM's indicate may be an indicator of a change-over in the way the fuel system works. I have an 02 SE and I've read in the brochures that a 2nd air plenum opens up under full throttle (and probably only after a certain RPM is reached). Resetting the ECU might solve the problem but probably only temporarily. My suggestion is that you don't try and reset the ECU. Take it to Nissan exactly as it is. The failure codes will still be fresh and accurate and may help them diagnose the problem. Intermittent problems are a ***** to resolve. Hopefully you purchased your car late in 200o and then the 3 year warranty period won't have expired. Good luck, and sorry I don't have a better answer.

 

i think it is a problem with your mas flow air sensor
my friend had a damaged one before and his car died on the highway
then it wouldnt go pass a certain rpm, i think it was 2500
the engine gets to 2500 then just drops down again like a fuel cut, is that what you are getting?

 

yeah that what is happening. does anyone know how to install the factory intake?? or should i just bring it with the intake on...

 

Take the aftermarket intake off, put the stock one back on. It isn't that hard if you have a simple rachet set and a screwdriver (assuming you put the intake on yourself).

 

how much does a mas flow air sensor cost??? that lil thing can do that to a car???

 

listen!!!!!!
you must put the stock intake back, cuz they will not give you warranty with the aftermarket intake
the mass flow sensor costs like 400 us i believe, so i dont think you would want to pay for it

and yes that little thing can do that to a car
when you see that thing you wouldnt believe it, cuz it is so small!!! its just a piece of plastic
that thing is supposed to sense the quality of the air going into the intake to the engine and the thing it damaged now, so it doesnt allow the air into the engine, and the engine doesnt run properly

 

Have you tried just resetting the ecu by taking the battery off for a little while. What you discribed sounds alot like the safe mode that my car went in to one night when I raced some one and rode it too hard to the red line in a lower gear. I would try that before I took the intake off and took it to the dealer.

 

1) i say listen to the first post and leave the car as is. DO NOT RESET THE ECU. if you do, and it solves the problem temporarily, good luck convincing your dealer that it was busted.

2) reinstall your stock intake system. no stock intake, no warranty service on maf.

3) talked to daveb today about my own maf. it's $400 originally, then somewhere between 2000 and 2001, nissan replaced it with a new part number that only costs $90. the new one is cheaper, and presumeably better, but there's a tsb to reprogram the ecu with new parameters if you go with the more recent one, which obviously you should.

btw, when you take your intake off to put back the stock one, look at that metal screen on your maf, i bet it's gunked up with crap. maybe it's restricting airflow too much?

 

hey serin
i m not tryin to prove you wrong or something
but i dont think they changed it at all between 2k and 2k1
cuz my friend has a 2k that is supercharged and some other work so he obviously doesnt have warranty
he had a busted one a couple months ago and i put his busted one in my car and got a new one from the dealer from him....
and my car is a 2k1 AE
so i think the only have the $400 ones
.......

 

MAF

Same thing happened to me, While I was racing a GTP

 

yeah, i see what you're saying. but that info is from dave burnette. he looked up the two different part numbers and got the costs for me.

 

from what i understand. the two maf's look the same, behave the same, taste the same. the only difference is something internal that dictates different ecu settings.

 

then im probably wrong on this one

so maxxxed out, you should just take it back to a dealer if it is that cheap
just buy one and replace it yourself
it takes like 40 seconds...

 

40 sec??? i've been trying to find a way to remove my maf from the accordian resonator thing without disfiguring it. what's the secret??

 

cost difference may also be due to different suppliers providing the part which would explain the different part numbers. just an idea.

 

so it is the maf??? did it break because i have an intake? it seems like alot of ppl have this with there cars due to racin or pushin their car...or are they just poorly built?

 

it might not be the maf, so my advice is that you put your stock intake back on and just take it to the dealer
say that you car just died on you....

 

im gonna go to my dealer tomarrow but i gotta drive about 40 miles.. think i can make it with the car studderin and sum times stalin???? wiil i do any harm to my engine???

 

By the way, if you are driving a 5spd and your car "stalls" while moving, simply push in the clutch, make sure the car is in gear and let out the clutch - the car will start.

You know it as a jump start.

 

Why don't you just take a look and make sure the MAF is plugged in still... Unplug it and plug it back in. You just may have a lose connection.

 

There does seem to be a lot of MAF problems associated with aftermarket intakes. I noticed that the PCV setup on the stock runs through the air filter before going into the intake manifold. The aftermarkets just run it straight in without filtering it. I am wondering if it is building up gunk in the MAF?

 

Aftermarket intakes filter before the MAF also.

 

The ones that I have seen have a straigt pipe that connects to the PCV hose. This runs straight into the air path without a filter. Which ones have you seen that filter the PCV flow? I would like to look at them.

Thanks,

 

I had a Stillen intake (pop charger) on my car. To install, you pull out the stock airbox, take off the MAF and attach it to the Stillen pop charger then re-attach in same position as stock.

So, the filter is in the same location as stock, it is just a pop charger instead of the stock box.

I believe the same thing is true on the Place Racing Cold air intake .

 

I have a 2k2, and I think the set up is different than the 2k's. The PCV flow on the 2k2 come in before the MAF on the stock setup and is filtered. On the aftermarket stuff, the PCV isn't getting filtered.

 

you should find someone with a maxima to lend theirs to you then you drive to the dealer with the normal one, and when you get to the dealer just changed it to the damaged one in a plaza near by

 

i just installed my stock intake and bringin it to the dealer tomarrow. think they'll give a hard time??? 0o yea i dont have the stock drop in filter ne more but sum other kind...does this matter?? also does ne one have a close up pick of the stock intake...cause just wanna make sure i installed it correctly...mAY B THEY'LL GIVE ME A NEW ALTIMA TO DRIVE FOR THE DAY TOO

 

cool. push for it

 

i got my car back today from the dealer and it was a blown maf sensor... i also told them to check on the fuel-cut tsb thing...i dont know if they did it or not but my car is runnin again! i have the stock intake back on and the car feels alot weaker or may b its just in my head. should i put my intake back on and risk blowin a maf sensor again????

 

what do mean it's blown? did the sensor thingy get fried or sumtin?

i doubt your intake had anything to do with it, or otherwise there'd be a lot more people experiencing blown mafs. i'd call it a fluke and put your new intake back on.

 

i guess i should put it back on since i still do have another year or 8000 miles b4 warentee runs out.
