Stagea M35 Engine Light On = Low Power

Hey groovers,

I bought a M35 Stagea Axis 2003 last year, mostly thanks to time spent lurking on this forum ;)

Anywayz... I have an issue I was hoping you might help me get closer to diagnosing.

The engine light comes on sometimes, and the car gets low power when this happens (crap accelleration with total max speed 40km/h)

Normally turning the engine off and restarting it does the trick, the light goes off and back to full power again.

Although sometimes it takes 4 or 5 restarts of the engine, (not good for my starter motor!)

The car then runs beautifully for days at a time, then I get the engine light issue a couple of times in a day.

The engine light more often comes on at first starting the engine.

But also, sometimes it happens while driving, at low revs (can be cruising in traffic at 50km/h then notice no power to accellerate and it's the engine light has come on, so drop gear back into neutral and turn motor off and restart a few times until light goes off)

It seems to help reset the engine light problem if I give the accellerator some extra gas when turning on the ignition.

If I dont give it extra gas when cranking the ignition, then it takes many more restarts until the engine light goes off (i.e. back to normal engine power again)

I called a Nissan performance mechanic in Melbourne and described the problem, but the guy I spoke to hadn't heard of this specific problem and wanted me to book the car in so he could run it on the dyno for testing.

I am cash strapped at the moment so can't afford a big amount of diagnostics and repair bills at this point

But thought I would post here just in case it sounds like some obvious specific part to be replaced (if someone's heard of this problem before)

At least then I might know what my target saving goal is before I take it in for repair$.

I'm pretty sparse on the mechanic side of things, but my guess is it's not getting enough fuel into the turbo?

Thanks for any comments and suggestions!!! :cheers:

The engine light means that the ecu has logged the error/ diagnostic code.

it is as simple as getting that code read, and replacing the offending article. Scotty should be able to read the code for you, he'll see this soon. He's in melb.

It will be either AFM, or one of the crank or cam angle sensors. The code will tell you which one.

Having the car on a dyno is ridiculous, so I suggest never setting foot in that shop again.

In the end of the day, a mech shop is not going to diagnose something over the phone, they want you in their shop so they make some cash off you.

Dyno? Is he serious? Unless you didn't tell him it was factory management?

But as mentioned above, run the diagnostic, get the fault code, replace the relevant sensor.

Car will be back to normal.

Just so you know fuel doesn't go into a turbo.. Unless you have anti lag installed ... That would be interesting.

Good luck.

Yeah I don't think he was really actually listening that closely to me, he just seemed wanted to book me in

I've read good things about that shop on the forum here, and I probably will go there for a proper tune one day as they are close by

sounds awesome :)

LOL yeah what a dork I am sometimes.... exhaust!

I guess I was trying to describe what it "feels" like when the light comes on.

No turbo. No power. Car feels like it is running in limp mode until restarted.

Hey Scotty if you're reading this I'm happy to drive wherever in Melb. I'm based at South Melbourne. Let me know the regular fees / deal for diagnostic, can PM me if u like.

It would be a relief to get some certainty about knowing what is the problem actually is.

LOL yeah it did seem way off base. Car should at least be running normally before going in for performance tuning eh?

Hey Mick I will reply to your PM shortly.

It definitely sounds like limp mode, and seeing as the car still runs I doubt it's the cam/crank sensors, perhaps another throttle TPS issue? They have been common lately. The Consult will give us a better idea of what's happening. Speak to you soon.

Your car doesn't need a tune up, there isn't such thing with factory management, it is not tunable.

Don't be fooled, all you can do is keep it well maintained in the servicing department and save yourself some money on that "tune up"

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      By sonicii · Posted

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
