Oh my god! I just replaced my MAF tonight and took my 2000 GLE for a spin afterwards. The beast feels like I put a brand spanking new engine in there.

I don't think I've ever experienced as much power from my engine in the entire time I've owned it -- so I've probably had a slowly dying MAF for over 2 years.

The following symptoms and problems are now gone:

first syptom, 2 years old:
- momentary "stutter" after putting car in drive and giving it a bit of load after a cold start (as if it skipped a beat)

started a bit later on:
- brief dip in power/acceleration at 3500 rpm

didn't notice it until the MAF was replaced:
- sluggish response

more recent problems, as the MAF got worse:
- surging, stuttering, stalling
- intermittent P0171, P0172 codes
- rough idle
- variation in engine power and performance at constant speed
- requires "babysitting" after cold start to convince the ECU not to stall out
- ODBII reported fuel trim >= 8-10% on both banks at idle, with occasional long term trim at 25%+.

My ECU reprogram is scheduled for tuesday morning. I realize I don't require the reprogram, but I presume there's new fuel maps for the updated sensor, which will only help power and fuel economy.

Short term and long term fuel trim are now both at -8 to -10%! That's quite the change from before. My air filter wasn't even particularly dirty when I replaced the MAF.

Thanks Dave B! You were dead on about it being the MAF. PS - Fedex got it here this morning, in one piece. They're even sending the GST/PST (taxes) bill seperately which means it didn't get delayed at Canadian customs.

YAY!

dude thats sick. yeah the guy who had mine had to replace his too. i hear that alot of people have to replace their MAFs bvecause nissan can't seem to get a good quality OEM manufactured. But then again alot of guys DO NOT need to replace. I guess it dpends on the car you have and how good its taken care of. I baby it now.

Same here Teflon. When my 02 se started having seriously long delays(only 10,000 miles) between shifts, I brought it to the dealer. They said it was a bad MAF and replaced it under warranty. It was like driving a totally different car.....very powerful and the tranny shifted like butter. A night and day defference.

I haven't feel any big power loss... but I might just replace it with the updated one and see if I'm used to power loss..... but let see

When one considers how the ECU works and that the MAF is a major input for controlling ignition timing, its pretty amazing that our cars even work at all with a bad MAF.

Anyone know the approximate cost of a new MAF for a 2k2??? Just curious.

frankd121

iTrader: (1)

around 500 bucks; they're a lot more than the ones for the 2k-2k1 which run for about 100 bucks

How much did Dave B charge for a 2000 MAF and how much does a regular dealership charge? Also, is there a write up for changing it out? Thanks

iTrader: (3)

that would be because he has a life, unlike the rest of us...

that's great to hear the difference in your car! I'm positive mine isn't anywhere near going bad, because it runs like new still ...but when it does go bad, thanks to the .org, i'll know what is the cause!

i recently got my SES light and went to autozone and i got a P0138 code and i have looked everywhere to find how to fix this problem. would a new MAF sensor fix this? any advice would really help thanks alot.

guys.... my service advisor told me that u could just replace the element itself for $140 + reprogramming! He said u no longer have to get the whole assembly!.... can anyone confirm this? he is talking about the 5.5 gen too!

2KBluePearlMax

I think Dave B charges somewhere around $85 for a 2k maf. Stealership is around $105-$115. Correct me if I'm wrong. The changout is very simple even for those who aren't mechanically inclined.

My MAF died around 86k. I replaced the maf and car came back to life.

iTrader: (3)

hmm the symptoms that u listed seem to be the same as my 2k..

so when i get a new maf and change it out, is there anything else i should do?

or is it just plug and play, and drive?

chris'smax

iTrader: (3)

can't you have a bad MAF without there being a code?

merovi

iTrader: (7)

yes i've heard numerous times that it is true. not sure exactly how to do it but i've heard that it is just unscrew the actual maf out of the holder and slide it out and replace.

Dave B is the man to call when you need parts for a cheaper price. He helps up ORG guys out!

it is not just plug and play. there is a write up and most people can help you out with the install. involves removing the airbox assembly first then tackling the MAF.

Hey, would you let us know if the reprogram improves anything? And how much is your dealer charging?
Thanks a bunch

I just replaced my MAF on 2000 GXE. Huge improvement. Solved all the symptoms at the top of this thread. Dealer wanted $199 to reprogram. They will lower that if you negotiate a little...

Is the reprogram absolutely necissary on 2k's?

More importantly is there a way to tell what version you've currently got so you don't waste your time with an update you don't need?

My MAF was replaced once and I believe (but am not sure) there was an update done of some sort. This was before I owned the car. I think it needs replaced again. Would you be able to tell if you've currently got an updated MAF off the part number?

There's a TSB for it and you have to see if the ecu part # matches the ones in the TSB. According to e55, 2002's and early 2003's have a bad fuel map and weak MAF's. It's suppose to cure hesitation/lack of power.

ses_again

Dealer told me it had to be reprogrammed because it had corrupted itself due to running with bad MAF and/or O2 sensor for a month or so.

Guess Im not alone in my nightmare

I'm just trying to fix my problem with P0138. It's the oxygen sensor and I'm pretty sure you would have to replace it, but not too sure maybe MAF would help it.

shurik

iTrader: (6)

Is there a phone # for that Dave B, and he should have those oxygen sensors, right???

imported_dan_m

I am a newbie and I have the same symptoms need to replace my MAF

Dealer told me to replace tranny and other mechanics mentioned to change spark plugs !@#$%^&**

instil

2001 owners who have replaced you MAF.....what part did you buy?
Im confused with all this MAF talk. I've read and re-read the posts,but all the clear answers apply to 2k,2k2 so i dont know what i need to do.

TDotMax

Thats what I thought to...But the MAF went on mine the other day...Totally different car now.

instil

exactly.i thought i remebered it being quicker when i got it,but then i thought maybe i just got used to it. then i drove someone elses car,and i knew thats how mine USED to feel. I hoping for good results when i change it

Charliejag

what part number is the 2000 MAFS? I know the entire thing is 22680-AD200, which has been superceded by 11680-AD201, but does anybody know the part number for the element alone? I don't want to spend the extra 300 dollars for the tube. Also, does anybody have Daveb's number?

Shogunsc4

iTrader: (2)

I think you want to try the 2001 updated (stronger) MAF...the part number for that is 22680-2Y001. It's a little below $100.

Charliejag

Will the 2001 work just as well as the 2000 MAFS? Also, will I just need to reset the ECU or will I have to have the dealer reprogram it?

tjmaxcoll

I have had the MAF fail twice since I had the car (2002). Once was under warranty. Does anyone know why the older 2000 or so MAFs are like 80 bucks and the ones for 2002 are 450? I can attest to the fact they are not a quality part and surely not worth the total 600 bucks the dealer charges to R&R the thing.

My latest problem is that it dies when the AC is on at idle. It starts back up fine. It just seems the idle is too low or the idle kick-up for the AC is not working all the time. Anyone with thoughts on this would be a great help.

How can I cantact Dave B and what does he have?

check out the sticky thread about 5th gen parts sites, his numbers in there i think

Dave Burnett in parts dept. @ Southpoint Nissan in Austin, TX. His #: 1-888-254-6060; that's a direct line to parts dept. Dave picks up about 50% of the time and he knows his stuff.

my maf should arrive tomorrow or saturday. Im very excited about the fact that my car may be quick once again!

My 2K GXE had the exact same problems. It's at the dealership right now...I'm going to have to sale and arm and a leg to get it back. I had taken it to AutoZone and got P0171, 0172, 0174 codes and was going to replace the O2 sensors but I didn't do it right away and then the symptoms got really bad...like I could have had a really bad accident trying to get on the hwy this weekend...the car just wouldn't move...the rpm was high but I was getting not action. I'm hoping mines is going to feel like a spankin' new engine too.
