I could be your MAF.

Maf......what Is That?

 

i had that problem too, about a year ago. I would be driving and the car would shake and i couldnt accelerate. However the car never stopped running but it seemed like it was goin to. The dealer told me it was the crank angle sensor and another sensor that i cant recall. didnt cost too much. Hope that helps a lil.

 

thanks a lot. i wil check that in monday...and i hope is nothing serios...tks again

 

was it a camshaft position sensor or a crank shaft sensor

 

so i went to my mecanic, and he said that since my check engine is not on, and the ECM doesn't show nothing wrong, the only thing i can do is wait till my problem got bigger..meanwhile what can i do....any advise?

 

Just a guess...On my 95 the ECU Screw that you turn to check CEL is broken (meaning that I can keep turning it with out it stoping). If I turn the screw just a little too much in one direction, my idle is way off and the car will not stay on. If you have been checking your ECU codes a lot you may have the same problem. try adjusting the screw in small increments and see if it works. Good luck.

 

i have never done that actually. i both the car recently i don't if the priviose owner uset a lot, but a check that, tks.

 

Its sounds like your MAF. I got one for sale to.

 

how can i be shure that is the MAF..since i don't have any codes...

 

Check the codes, and most likely it will be the MAF, mine did the same thing for about 2 weeks on and off. I pulled codes, the CPS (crank pos sens) came up I changed it, still stalled. And on the second week, after I changed the CPS, even though I had checked codes at least 5 times before and nothing but CPS code showed, the MAF code finally showed up, and you can get them (MAFS) used for $35-75 www.car-part.com which lists junkyards across the nation, or from someone on here which may be a better bet since you may be able to trust some of them more. Total aprts was 100 dollars fofr bth sensors, and they are easy as pie to change. I'd bet its your MAF, change that before your CPS, get it used its a lot cheaper.

 

i have a question? if i don't have the check engine light on, can i still pull out codes..?

 

I am not sure about that. But i had a 1993 Maxima. It stalled once in a while. It ended up being the MAF. My suggestion is to take it to the Nissan Dealer and get it checked out. Thats if don't wana blow money on stuff that u don't need. Take it from my experience.

 

I will sell my MAF for $60 shipped.

 

i'm gonna check the MAF tomorrow, see if is this one..

 

Dont take it to Nissan, just to run diagnostics is $60 +. If you're going to take somewhere take it to Autozone and they will run diagnostics for free. Like I stated in my post above, my MAF code didnt show up until a couple of weeks after the problem had been occuring, and i had been checking it at least twice a week, shell out 45 dollars and get a used one, if that's not it, send it back. And to pull codes, read the STICKIES if you haven't already, they show you how, step by step. Not trying to be a d!ck, just trying to save you money.

 

i allready read it....and will do it...as for the maf i can find it used to...a have friends...as fore the Nissan dealer i absolutly don't think to go there, cause i live in tijuana and it's a lot more expencive here...especially for car like that...thanks anyway...if is the MAF i will let you know...

 

It could be a fuel delivery problem. Something as simple as a clogged fuel filter. I'd change that if i were you just for my peace of mind. Only 12 bux or so from the dealer.

 

my mecanic clean this one, but not changed..i was thinking to do tune-up, beacuse the car for me is new and definitely needs a maintanance. they changed the IAC sensor if a recole or IAC valve i'm not sure.

 

How the hell do you clean a fuel filter?? A fuel filter is not serviceable. It needs to be replaced.

 

yeah, I'd flat replace the fuel filter. Also are you noticing that you are idling really low (200-500) when the shaking/stalling happens? If so, there is a very good chance that it is your ECU screw, as I had mine too far to the left, and while my car would never stall, it did complain a bit. I adjusted it back to the middle and everything is dandy now.

 

Wath do you mean by idling really low........do you mean the rpm or what....sorry the ignorance...but first don't know a lot of this thing, second my english is not so good......

 

If it dies after operating temp, check the egr valve and make sure it is cleaned....if it does it when you start the car then check the ignition switch...there was a (should have been) recall on the ignition switch where two wires are soldered together. I also had this problem and doing both fixed them. Hope this helps>

P.S. Ig switch is located behind the lock thingy on the steering wheel column.

that happened to me but it was my ECU i didnt reset it properly

 

Had the same problem but I had a CEL for a bad MAF sensor. Tested the MAFS it was okay. Problem was solved by cleaning the connectors to MAFS; you can give it a shot.

 

I understand now what you mean, and i check it and when i'm idling the RPM is 700-1000. but sometimes the pointer star to dancing and shaking like crazy till it stops. yesterday while i was in stop the car start to stall, and the RPM was like crazy to 600-10m and then to 0 and stop. why it that happening? could anybody explain this to me.

 

I Changed The Mafs And It Seem That Everything It's Ok..for Now The Car Is Fine..i Hope That Stay's That Way...tks To All That Took Time To See My Problem And Post Me Something.....
