Ever since I got my car I noticed something odd about it. It pulled great in the low range, (a great improvement over my TL), however power seemed on and off at high RPMs. It would come on and go from 4000-6500. I felt like it didn't have as much power in the high range as I expected. Another worry was that I didn't feel like the car was as fast as my old car. It should be at least as fast if not faster. I remember the time when some Chevy pickup truck beat me from a dig at a light until about 50 mph. Granted it was a new truck, it wasn't a performance model.

Currently, my car is at the dealership, hopefully getting a new MAF when I pick it up.

Like I said, I think the car had a bad MAF from the day I got it.

Should it be a lot better than what I've seen/felt so far?

 

new MAF might solve your problem but problem could be related to something else.

 

I just picked the car up from the dealer. My extended warranty covered the diagnostic and repair. Apparently the MAF was signalling wrong to the O2 sensor to make the car run lean. That is what is stated on my receipt at least. The total cost of the sensor and the repair and labor was, get this, $215 and some change. That is the whole assembly, the tube and all. I can prove this because they left the stock tube on my passenger seat. The new one is much more clean, with shiny, not rusted, bolts.

The difference is remarkable. The car drives better now than it did the day I picked it up, which was little over 5 months ago. There is so much power in the high end, I love it!

I'm even more hesitant to install my Berk Intake. Should I be?

 

Why should you be?

 

i ran a berk intake on my standard maf for about a year with no issues and now i have the updated maf with the same intake. that is not to say that something could not happen but i have not heard of any instances of anyone blowing the updated maf.

 

Are all the replacement MAFs the updated ones?

 

the updated maf has been out for a while. everything in just about every dealer should be the updated maf. if you have any questions just check the part number.

 

Maybe this weekend! Now I just have to finish this 10 page research paper.

 

Which dealer did you have do the work?

 

Who's asking?

 

Me? Not sure how to answer that question. I just have found 0 reputable Nissan dealers to do work in Cincy.

You seem happy with the work, hence the question...

 

Sorry, I didn't know you were from the 'nati. Falhaber Nissan on Colerain. I was uncertain the first time i brought it to them. Since then, however, I like them.

Service manager to talk to is Jan.

 

Yeah, I used to go there until my service writer left. Bob was cool and let me bring/use my own materials. Then he "left" and some dufus tried to sell me a coolant "flush" (You know...mandatory to keep your warranty kinda sales job) when after further questioning it was brought to light that they dont flush anything...they just drain and fill. I asked if I could use my own coolant and he said "Absolutely NOT! We NEVER let customers bring in their own stuff" I explained to him how I was able to with Bob and he got down right nasty with me...So I went back to my car and left. He actually had a dumbfounded look on his face...

Glad you had good luck with them though...I guess I just draw the morons out for some reason..

 

what is the diff between the old maf and the updated one? how do you know which one you have?

 

the part number on the tube or you can do it by your production date but i dont remember when they started using the upgraded one from the factory but i know they would be late build 01.

 

My new MAF doesn't have the special "security T... etc." bolt. It is just a normal hex. Is this the same for everyone else.

 

What is the part number for the 'updated' MAF, please?

 

but what is the difference?

 

Just changed the original MAF on my 2000 to the updated one last week. (Have the Berk intake) Keeping the orignial as a spare. Slightly smoother idle/acceleration now.

Part number for the 2000-01 is......22680-2Y001.

One difference I noticed is that you can't see the wire inside the MAf like you can with the original. Seems the wire is hidden, maybe to give it some protection from stuff that gets past the filter.

Anyway I am hoping with the new one in place I won't have to worry about it blowing like the originals seemed to do under WOT.

 

what happens when the maf blows, how does your car feel?
