Not sure what is going on. Wife has been driving the car for over a year (I get it on weekends). There is some hesitation on full throttle. Kind of seems to be cutting out. I have 70k on the car seems to be the plugs but I changed the plugs to Bosch platinum 4's about 6 mos ago. Always keep the air filter changed. Any one else experience this? Or can give any clues?

if you have an early build 00 then you could have a failed coil issue. many early 2000 had problems with coils failing and there is a tsb but you are out of warranty but the good news is that they arent that difficult to change yourself. the only other issue i could think of is that 4th gen guys swear by NGK plugs and when they used bosch +2 or +4 they had problems shortly after. i would change the plugs to either NGK coppers ($1.59) or platniums (8.00) and if that doesnt resolve it then get the coils replaced.

my car is ****ed up
it stalls all the time

I'm having the same problem. I get detonation knock under hard throttle. Other times it acts like it's running out of power or bogging down, kinda like when you press the brakes and gas at the same time. Spent$265 at Nissan for Mass airflow meter. Was a little better. I guess I'll try the coils next.

definately coils.. they are more prone to failure than your MAF (pre-02).. after the MAF, its O2 sensors but those will throw a code/SES light

You may not have a coil problem. If your symptoms are JUST the stalling, then there may be another problem/cure. Your symptoms sound a bit different than skalberti.

There have been two other solutions to the problem that you have.

One, clean the throttle body.

Two, (and this is what solved my problem) have the fuel cut tsb done. My car was stalling at red lights. And I could make it stall if I went full throttle for a couple of secs and then pushed the clutch in, shifted to neutral and braked. (as you would do if a light suddenly turned red).

I believe they adjusted my throttle a bit in connection with the TSB. Hasn't stalled since.

Also, if you've added an aftermarket intake, air getting in behind the MAF could cause a stalling problem as well.

Well i did clean the TB...its was not dirty...
I have a frankencar intake on
But before i put it on my car stalled a couple times
How do i adjust my throttle....there are two wires
One moer thing...around 3500 rpm's my car really does not excellerate
it just kinda doesn't move...
its really ****ing my off
I had an accord before and i never had problems with it, as i do this my maxima
please help

You can't adjust the idle manually. It must be done with the computer. I believe that any shop with an OBD II reader can adjust the idle - but I may be wrong.

If you can't accelerate after 3500 rpms, then it is not what I suggested in my earlier post. It is either

1) Air getting in behind the MAF.
2) Bad Coils
3) Bad MAF.

When my MAF died, I couldn't get the car above 3000 rpms and if I let it go below 1000 it would stall. I had to shift in between those two parameters and only give it a little gas. I mean the car was barely driveable and it took me a while to even figure out how to get it to move. It is much harder to drive a stick with a bad MAF than an auto.

like maxgator said you cant adjust the idle with the throttle cable, it must be done with a consult 2 but you can adjust the tension on the throttle cable.

yeah.. I agree, stalling wasnt really the issue with coils, it was under load that they would start malfunctioning.

Hmmm, stalling? I would change gas stations as a precaution.

So We have 6 Coils in the Car. Do we replace all 6 or is there a way to tell which one is bad?? I just changed my Plugs with Nissan plugs about 1500 miles ago, and It hardly made a difference..

sloppymax

iTrader: (8)

even though they dont throw a cel, i thought you could still use a diagnostic machine to tell which number coil is bad. how many miles did you have on it before you changed and i assume you went with the platniums since you said nissan plugs?

PIONEER

Car has 55K miles on it. Just changed plugs, drove to New York and Back.. no difference to me.... Now get this.. It only does it sometimes. Not all the time. I took my car to the dealer, he put the OBD II on the car, hell all kinds of readings were wrong he said, he said the cats were missing, the Stock airfilter was missing .. I said what you mean I have 2 precats missing .. I have a Y-Pipe but I was like you sure the car didn't come like this But he said the coils were good, and he said based on the readings, It might be the MAF but he had no way to prove that b/c the cats were missing and the facory air filter system was missing. I have a Place Racing CAI.

Which problem are you having? Stalling or more than that. If just stalling have you had the fuel cut tsb done?

PIONEER

iTrader: (1)

Just when I press the gas, its sounds like it doesn't wanna go and Bogs down, and you hear the chain.. but if you ease off the Gas its allright. but only does it sometimes, not always.

sloppymax

iTrader: (8)

did you gut the precat on the back of the manifold?

PIONEER

iTrader: (1)

My car is Fed Spec, so my Y-Pipe is 1 piece, 2 Pre-Cats.

Max_Gator

I think he's only got two - and both are taken out by the ypipe. 2k fed spec.

I'm having the stalling problem too, I raised the throtle a bit. I want to see if there's a different way to fix it though. when you guys say to fix THE CUT TSB...what is that? and is it easy/inexpencive to do?

thanks

Max_Gator

The FUEL CUT TSB is what I'm talking about. It only applies to 2k/2k1s. There is more info than you could ever want on this site about that problem. Essentially, the way the computer was programmed caused drivability problems.

However, several of us have learned that asking the dealer to reflash the ECU with the updated programming solved the stalling problem I described above.

i have the same problem but my car stalls too
why can't my car just run right

I think they do throw a cel. Well, in my case they did, and yes, ODBII code tells you exactly which coil needs replacement.
One suggestion though - try to reset ECU (unplug battery for a few hours), I found that it helps in a lot of situations. Worth a try.

Good luck.
