Might be too early for spark plugs...but...

Make sure all the spark plug wires are securely in place and has no cuts on them.

Did you do the 30,000 mile service?

 

Thank for your replies... I don't have an update, and it hasn't stalled, and i havent gone to the dealer.

Im not sure where the PCV to plenum tube is...i guess i can snoop around under the hood.


thanks for your reply!

Sunny

 

Update....

$51 dollars for 30 min diagnostics, $30 for gas, and the tech at nissan took the car home (45 min drive through). Did not stall once....no cel lights, no leaks...

They said, don't do anything, and try to take us for a drive while it stalls....


I took it to the stealership because the problem was severe...and it was stalling at every light.

I guess its a process of elimination now....perhaps change the MAF and fuel filter? I have cleaned everything, did the throttle relearn, replaced the air filter....have not bumped the idle...

 

Update: Nissan finally got the car to stall, and they have tried everything. The tech thinks its a case of "blow by" (no clue)...something to do with excess oil.

They are calling Nissan Canada to obtain authorization to get me a new engine


Hope they authorize it!


I'll keep you guys posted...

 

Most likely because of a compression problem. New engine for you

 

I'm having similiar problems with my 2004 350z roadster after I had my oil changed and the exedy clutch and flywheel install. The RPM drops below 500 and stalls. When it doesn't stall it'll bounce back up to around 800 rpm at complete stop. Is it my lighter flywheel? or is it too much oil during the change? Or do I need a new engine (hope not!)?

Any suggestions would be appreciated.

 

So was the tech right and it was "blow by" or is he still working on it?

 

Did you use 5 cans of fule injector cleaner all at once? Or 1 per tank, over 5 tank fills?

 

I have my car at the stealership right now for a low idle. It was getting to somewhere around 500 RPM or so (after warm-up) and felt like it was going to stall out a few times.

The dealer is replacing the MAF unit right now (hopefully, under warranty).

Just something to check for those that are experiencing the rough (low RPM) idle.

 

Did the MAF replacement work?

 

PROBLLY THE TIMING!!!! check the headers, if they are cherry red after a few min of ideling and if your car backfires at all during idol then thats the proble, it happend to me today, i did a search on yahoo answers and i thiink thats the problem!!!

 

I just changed the oil and I'm having this same problem.. Driving around, come to a stop... dies..

It's not a vacuum leak as pressing the break has no effect on the idle.

 

No read hot and does not backfire. Actually drives like a dream but only when I come to a stop does the engine cut off. Does not throw any codes. GT motorsport says I need to increase the idle by using the technosquare flash. I've just been waiting to see if there is any other solutions so I don't have to pay for the technosquare

 

only an oil change or other mods?

 

ask the dealer to perform an IAVL.... or do it yourself

 

Only mod is a pre-existing Injen Intake.

 

Tried that already. Nissan dealer said it didn't work because the idle was so unstable and GT Motorsports said it doesn't work for 2004 models.

 

The stall happened after my clutch and flywheel install. Frustrating.

 

if the dealership can't get it to set they should have recommended a throttle body. GT motorsports is wrong, its a function built in to all VQ's due to the E.T.C.

could be related to the U-TEC also, seeing as how it does have idle control functions(I.E cold start, a/c bump etc)

 

Cleaned the air filter, sprayed the maf. Problem gone, I'm geting 2mpg better now too.
