M35 Stage Problems

[[[d a n n y]]]

mate bought a new stagea (m35 ARX)

imported it himself..

it drives fine...

but it's got a few issues..

firstly...

idle drops rapidly and stalls after it's given a hit. some times it stalls once it comes to a half even in normal driving..

fuel pressure was low when we checked it

so far we have replaced the fuel filter and the fuel pump and that has brought the fuel pressure up

but the problem is still there and but it has become driveable...

still idles very low...

does any1 have any ideas or have faced similar problems?

Mine has done similar things.

Used to stall when breaking hard and revs would dip and then stall. I have reset the Throttle Position Switch (TPS) which seemed to temporarily fix the problem but idle was a bit too high at 850rpm.

Recently the problem has got worse with the car stalling whilst driving. Some times when coasting other times when accelerating. It is also hard to start now. Also have check engine light on dash. (this may be a similar fuel pressure thing)

I have the car booked into Nissan for a service on Friday so it will be interesting to see what fault codes are showing and what they mean.

The car has 78K on it and has not had the plugs replaced so I am thinking this may be contributing.

Other things that I suspect may be problems are power steering fluid (as I saw this was a problem for another M35) or possible the O2 sensor.

Any way I will post up what it turns out to be.

Have a look at the "Stagea Stalling" thread as the way of getting the codes and resetting the TPS are in that thread.

Cheers

yeah just noticed it too...

i guess i got to do a few things to it first..

ill try the TPS and then the power steer flush

[zei20l]

so his one has a fuel filter?? where is it? i cant find one!

i rekon do the plugs also while youre tinkling, you need to take off the throttle body to do the plugs, so give it a good clean. its possible one of the vacuum lines that go around the TB is blocked. hit it with some cleaner and see how that goes.

I had similar issues. I took mine to Nissan and they flushed the power steering fluid due to it being a bit gluggy, which improved the steering a lot and I'm thinking this may have been putting intermittent strain on the drive belt - causing the revs to dip and sometimes stall. It hasn't stalled since I got the car back (just over a week now).

However it does still rev low (500rpm) when idling and occasionally the idle has a tiny shudder.

I've tried resetting the TPS switch, and I've done the Idle Air Volume Learning procedure (which it sometimes just stalls during) but nothing's really changed. The ECU is throwing no faults, and the transmission fault code said something about CAM or something - its to do with a communication link and didn't appear to be an actual fault. (code 17 or something)

Other things I may try in future is spark plugs and fuel filter (does it have one or not?).

Mine's done 92000km and so it will be due for new plugs soon. Will be due for the 100,000km service later this year so hopefully it holds up till then.

The M35 has a timing chain, not a belt, so servicing costs for the big 100K will be much less - woohoo!

Actually now that I think of it - Nissan were going to check the plugs on mine but because the throttle body needs to come off, they needed a new gasket which they didn't have in stock so weren't able to do it.

There were quite a lot of things they weren't able to do due to parts, but they were very helpful in at least looking it up and having a go. They were still able to service it and rot&bal the tyres which is what I originally put it in for...so it wasn't all bad.

They weren't put off by the extra hassle either, and offered that if I need any parts just to let them know and they'd order them in. I'll definitely be going back

I cannot find the fuel filter either.

If OP can tell us where it is, that would be a great help as it was my understanding that there was no fuel filter on the M35.

Perhaps he means the Fuel Pressure Regulator??

Coming up to 150,000kms. Changed the plugs at 110k. Put in a good set of Platinum or Iridium plugs. Makes a BIG difference.

If you want Iridium, try the Denso plugs (will have to contact Denso themselves and import them).

We put them in my mates stag (I just has the Nissan/NGK platinums put in) and it idles much smoother.

Have my Denso Iridiums earmarked to be put in at 200,000kms.

I had my car diagnosed by Nissan today for why the motor just stops when running. Also difficult to start.

Error code was 304, It is the Crank Angle Sensor on the right bank.

Will have it fitted on Monday, cost $340 fitted.

Lets hope this solves all my problems.

will not solve all your problems!.....but you car might be fixed

Shit, If I could solve my problems that cheaply and quickly I would be there in a flash.

Lucky for you they still can't work out your problems so nothing to be done at the moment.

[[[d a n n y]]]

found the problem

had to use another M35 for this but

it was the TPS module that was fuaulty

[iamhe77]

[[danny]]

Still curious about this fuel filter change.

Details?

[[[d a n n y]]]

ill get the exact details for u

my mates mechanic did it

[andy65b]

Ahhhaaa. I have it.

It is inside the fuel pump in the fuel tank. It is a Fuel level sensor/fuel filter and fuel pump all in one.

Pull out your back seat and you will see the tank under the seat. From what I can see on the pics, there will be a large round section on either side of the car. One side, I think the drivers side will have the unit. It will have a single lead coming out of a rubber cover that looks to go towards the front of the car.

If you have the G35 service manual have a look in the file FL, page 5.

I will have a look for the part number tonight.

Cheers

hey anydy maybe your car has the same TPS problem???

No I had fault code "340" which is the crank angle sensor. But then again, maybe it has both faults.

[zei20l]

thats not bad for a CAS price new from nissan! im surprised, but then again the VQ is a current series motor and im guessing they all use the same part.....

as for the fuel filter, is this a servicable item? ie does it need changing or is it a 'sock' or strainer type of thing??? or is it an actual filter with an element in it?

It is a little bit difficult to tell from the images in the service manual. I will look for the part number tonight and that, with the price may give you a clue.

Me, I have no idea.

Agreed.

I have attached the FL.pdf from the 2003 G35 Sedan for those who do not have it.

As Andy said, flip to page 5.

It is a Fuel Strainer (NISSAN part number 16400-4M405) but if first owner in AUS their should be no need to replace it as they are a requirement of compliance.

When ever I fit the strainer I always replace the O-Ring as a slight cut or crease can cause fuel leaks so for the few dollars to Nissan it is worth it.
