Mass Air Flow Sensor Problem? HELP

Import_nights · Oct 24th, 2005, 08:59 PM

I am in terrible need of help! What happend was after stopping for traffic in my 02 Spec V my car starts to levitate, or retards itself once it hits 2500rpm and won't pass it. i am able to keep driving but i have shift befor i hit 2500rpm i can make it up to about 50mph in sixth gear but if i hit 2500rpm it retards itself.

I have an aftermarket short ram intake filter that i bought from autozone i have never put any oil on the intake filter and it looks somewhat clean so it can't be that.

i tryed to clean the sensor but still don't work.

When i start the car it idles between 1000-1300 rpm it normaly idles at 600rpm and i can give it gas but once it hits 2500rpm it retards. i checked the surronding wires and fuzes and everything seems ok.

Is there anybody else out there that has had this problem? Nissan wants to charge me $400 something dollors for JUST the sensor. i plan on putting it on myself but that is still a very high price for a little sensor.

Thanks for any help

are you throwing any codes?
try the idle relearn
chances are you blew the maf and you need a new one (buy a used one for like 200 or less)
when did you install the filter

ya i went into the dianostic mode deal where the SES flashes you a code, and i reset it but to no prevail, so i am assuming the worst so now i have to get a MAF i think

i have had the intake filter for 3 months now and i cleaned it just 2 weeks ago by just putting hose on it and letting the sun dry it out. I don't have a true K&N filter so i don't have the oil crap on it.

Ya after reading the code this time i found out it is the MAF, so i'm thrilled luckly there is a friendly fellow that is selling me a used one for 125$ from the V board

thanks for the help i really apprecate it

It's an easy part to change. I had the same problem twice now. That's what I get for buying cheap used parts. I've seen some MAF's on ebay, so check there.
