Don't spell it that way.

Yes, I'm a newb, and I have a question concerning my girfriends 2000' Maxima. Her car has been running funny here lately. Start it in the mornings, and it may shut right back off, then start up fine. While driving, it hesitates as if its running out of gas or skipping. CEL is on, so I pulled the codes last night. It came back with P0171, P0174, and P0300 which said, Bank 1 and 2 lean, and multiple misfires. Led me to believe it was the fuel pump/filter, but as I read here on the forum, its sounds like the MAF meter. Any suggestions? Thanks in advance.

I'd say MAF and coil packs.

For the MAF:

It has definitely been running lean.. not rich. IF you see my old post - all the symptoms point to a lean mixture. If that's the case, why do you think I threw a p0138 and p1147? It happened, I cleared them, and they haven't come back in a few weeks. I'll do the MAF test this weekend. Thanks for the info!

I'm going to pick up a good used MAF from a local junk yard and install it this evening and reset the CEL, and see how it runs. It doesnt do this the whole time its running, but its very noticable. I'm gonna test the existing meter before swapping it out also. Thanks for the help.

Throttle Position (TP) SENSOR

This sensor has the dual function of informing the ECM about the throttle valve

position and its opening and closing speed.

have had my '03 max now for about 4 months and have noticed that my steering is kind of loose and the wheel vibrates when I reach 60-70mph on the highway. Anyone know the cause?

BCoon

According to those links posted in the reply above (post 5044), it seems as though the MAF is more likely the cause than the O2 sensors (see post 5025 and 5044 in this thread for history).

The numbers I pulled off the MAF - which were almost impossible to see:

22680 6N200 AEEE002
A36-000 A00

In that second thread linked in post 5044 above (thanks NmexMAX), the MAF from the 02 is 6N201; mine is 6N200. IS there a difference between a M/T and A/T? I have a M/T. I plan on going the cheaper route of getting the 2K1 MAF and moving the IAT over.

Is there a tutorial anywhere on this process?

I still don't know why I threw those codes (p1147, p0138) - they haven't come back.

BCoon

In my original post (5025), I asked how much it would cost to get the ECM updated.. anybody know?

Does the update depend on what parts (new/different MAF) are installed or is it a general ECM upgrade?

I'm assuming if I replace the MAF myself and get the ECM upgraded, I will solve both problems listed in my original post..

MT/AT does not matter re: MAF. I've had a TSB done for free, but worst case, they might try to charge you an hour of time. Call your local dealer and ask them how much they would charge for the TSB's in question.

Jime had some great pictures on his server, but it crashed a while back. All I can say is transfer the thermistor from the 02-03 MAF to your 00-01 MAF, very carefully. You'll know which piece it is because one MAF has it and the other does not.

Odds are you will need the ECM update in order for everything to work well, it might also help in your hesitation issue.

Two questions:

Where can I purchase a High Stall Torque Converter for a 2001 Max?

I noticed egdgeracing was the popular choice a few years back, however, it seems they are only offering converters for Chevy, Ford, and Dodge.

http://www.edgeracingconverters.com/products.html

Any other suggestions?



Also, what exactly are these trans kits being sold here? (I assume its a diy valve body kit, no?)

Any help would be appreciated, thanks.

is that the cause why my car is not startin on and i put it the computer and the code is p1224

coil packs

I'm actually having some body work done on it from a wreck I had.. maybe they'll go ahead and fix that stuff since it will already be in the shop..

Thanks bro

impalasscars

Thats the route I'm going to try if this MAF doesnt do the trick today. Dont wanna go off buying a bunch of parts for no reason. The sad thing is, she just paid the car off Friday.

BCoon

Ok tested my MAF according to the first link in post 5044 above.. got the following, seems like it checks out OK:

Red 5.12v
White 1.32v
Black .01v
Red/Green - 13.5
Green/Yellow - 2.93

Now what?! According to that post, my MAF is fine. On top of that I have no codes! But my car has to be running lean - high mileage, low power...

Again, I had to O2 codes, cleared them three weeks ago and they haven't come back. Now I'm lost.

Yeah MAF wont give you misfires so thats why i'm leaning towards the coilpacks, what you described is what i had happen to me. You can replace just the one or two bad coil packs but i didn't wanna take the chance, since once one starts going bad the rest are sure to follow. I got a set of ebay for like 270 shipped

FIXED grammar plz don't type slang over the internet it doesn't make you cooler

00MaximaGLEgrl

Hi....i while ago i posted that my 2000 GLE was throwing the P0420 code....i took it to get inspected and it failed (which i knew seeing as though the CEL was on) so they cleared the code and told me to drive a couple hundred miles and see if it came back on. well it didnt and i went and got reinspected today. but on the way there i stopped at a red light and i could smell that egg smell really bad and i was the only car around. and when i got to the dealer the car stalled not long after i put it in park (it does that only after ive driven it tho, it always starts back up). well after they inspected it i told them about the egg smell and the guy asked me what gas i use. before i could tell him he assumed that i used regular and told him no i used premium and i have used premium since i bought the car. then he told me i didnt have to use premium because that could ruin the catalytic converter because not all cars need premium. then i told him that the owners manual said to use 91 octane or higher. then he thought i had a 4 cyl engine and was surprised when i said i had a 6cyl. so the guy told me that i needed to change where i get gas from (i.e. if i always get Shell switch to Mobil or vice versa) he said that alot of times the egg smell is from whatever additives they put in the gas and different places use different things. and he said that could be why the car stalls. now i dont know about any of you but i really dont think this guy knows what hes talking about. then he told me if change gas stations and i still get the smell and its still stalling then to come back. does anybody have an advice for me???

impalasscars

I swapped out the meter. The one in the car was missing the elements? I guess they fell out somehow. Hopefully they went threw the exhaust. Anyways, the car is running better until you stop at times. It doesnt want to idle for over a minute or two. It suddenly dies, but starts right back up. Then it will idle for another min., maybe 5, then die. No codes now, just and idle issue. We are using a used MAF meter. Any suggestions?

Sounds like a maf issue now still, coilpacks tend to cause stumbling and rough idles but not outright stalling. Any way to get ahold of a decent scanner?

impalasscars

I have a ODBII scanner. No codes are showing up when it stalls.

Anyone?

Yes they are DIY VB kit's, I prefer Drivetrain.com though. As for TC, maybe try contacting Edge, you might have to send one out now, That's the only one I remember.

what dose it mean When the injectors stayin open? on 03max

KRRZ350

iTrader: (29)

it could in fact be your primary o2's are shot. I've seen it twice recently, primary o2's didn't give any codes, but lean codes were present. Upon removing the o2's and shaking them you could hear the distinct "junk o2 rattle"

KRRZ350

iTrader: (29)

Why do you think your injectors are staying open?

Short in the ground signal wires between the injectors and ecu

BCoon

They initially gave p1147 and pending p0138. I cleared them and have yet to see them come back (I guess about 4-5 weeks so far).

Both pertain to oxy sensor 2, bank 2 (HO2S2).

Would that be the primary O2 sensor?

In response to my original post, somebody mentioned that a bad O2 would cause a rich mixture and a bad MAFS would cause a lean mixture. Sine all my symptoms pointed to lean, I just jumped on the thought of the MAFS going bad instead.

Was that poster correct or no?

I have to ask this are all of our doors EXACTLY the same from 00-03?

Fit wise cause I have an 02 that needs doors and not sure if the doors are same fit throughout the years of 5th.....
