I had to start a new thread all though theres one already.

Im happy as hell, my car has been acting funny and some days it feels really slow.

Today i went and got a MAF unit for a 01 max, 100$ with tax from my local stealership.

When i hit second gear the tires spin now for a good 3-4 seconds, before i was only gettin a lil hop.( They're 235/55/17 tires)

Im glad i finaly did this.

Swaping the little heat senor was a biger pain than I thought , couldnt get the thing out!

But all works well and I have no cell.

 

Sweet, time to re-dyno and possibly retune. Are the SAFC readings any different?

I carry an 01 unit in my trunk toolbox for 'safety' reasons.

 

any advantages (besides price) or disadvantages to installing an 01 maf into an 02?

 

Advantage is that it's a better more reliable unit, and it's much cheaper.

The disadvantage is that you have to transplant the IAT sensor.

YES I just replaced my crapped out 2k2 maf with an 01 unit, The MAX now runs like new again.

I would like to take this time to thank everyone whose posted on this subject in the past, They saved me over $300...........That I can now spend on a locker for my jeep

 

Glad ur cars runnin like a champ again. Just curious, did you get those codes cleared or figure out why they popped up?

 

Probably because the MAF went bad

 

I did the gas petal trick to clear the codes that were set when the MAF took a dump.

 

I never had any codes, my car just felt slow.

The other day , i dropped her down to 3rd at about 75mph and it felt like I was towing something, rpm barly climed.

As far as reading on the safc, I gained about 1% aif flow
Highest now is 73%,

I used to go to 72% on good days, lately it was hiting mid 70's tops.



ill see in a few days, the codes come up after about 100miles?

 

i replaced my MAF on my 2001 AE maxima and now it drives like new once again!

 

I'd hate to even ask, but the swap seems to be for the 2k2 to 2k1, is there any advantage to swapping the 2k1 to the 2k3?

 

^^^Post #4 answers ur question.

 

so dave how hard is it to switch that heat thing. got any pics, any write ups?

 

^^^ It shouldnt be too hard but not too easy either...Im wondering if the 01 MAFs have a place inside of them for the heat sensor thing tho

 

Yea, I plan on replacing my 2K3 MAF with a 2K1 MAF soon because I got a CEL last week. Car was feeling sluggish before the CEL went on. Call DaveB for a good price on 2K1 MAF.

 

UPDATE:

Im also gettin better gas milage.

Reset it on when i got on the highway. And durring my 30 mile drive the work the avg was 33mpg doin 70mph ,my car has never seen anything in the 30s before.
And around the city ive been getin around 23, it used to be around 19


Still got the cell for my rear 02 sensor that are running o2 sims.
Im thinking of puttin a resistor for the heat wire.

 

just got my MAF replaced at the stealership.....grrr but HOLY **** MY CAR RUNS LIKE NEW, not bad for a 00 with 116k
and no other problems( knock on wood)
