havnt cleaned the airflow meter.

when i did the spark plugs all the electrical plugs seemed fine, what exactly should i be looking for tho? and what is AFM?

Changed the fuel filter, and cleaned my air filter but ill buy a new one 2moz.

I didnt reset the ecu after doing the new spark plugs, but did it before hand to hope it fixed it before doing the spark plugs and also took it for a spirited drive.

Just to make sure, to reset the ecu, you unplug the - terminal off the battery, press the brake a few times and turn lights on for a few minutes, then wait 30mins and reconnect. correct?

hmmm...

AFM is Airflow meter. CAS is Crank angle sensor.

Reseting the ECU should only need, disconnect, pump the brake for 30secs, reconnect but you can leave for longer or overnite etc if you wish.

Just check for dirty or bent contacts etc...

even try jiggling wiring while it's running too.

Try diconnecting each coil 1 by 1 and see if it stops it. It will only be running on 5 cylinders at a time but if one of your coils is goosed the chugging shouldn't happen when disconnected.

haha i feel so dumb bout asking the AFM now, i should have put 2 together LOL!

ok well ill look on the forum on how to find and clean the AFM and CAS, and tomorrow ill reset the ecu and put in a new air filter, ill make sure the tyre's are straight because i've been warned about the HICAS.

Just curious to why resetting the ECU would fix this, and should i do that everytime i fit parts?

Im quite new to most this mechanical work, ive only done a few things before, so i apologise for my lack of knowledge, but im learning :D i love SAU!!!

It's all good mate. SAU is a bottomless pit of Knowledge. :thumbsup:

I am an Eternal n00b myself but always learning. :D

ECU reset can be a good thing with new mods but isn't really necessary and can fix things (sometimes).

Example... In my 94 Bluebird, it had a weird thing going on which I was told by a mechanic was my injectors packing in.

I had it to a different mechanic who diagnosed and fixed a leaking intake gasket but the weird lumpiness was still there.

I Reset the ECU and suddenly the weird lumpiness was gone.

CAS I would unplug and clean the contacts but don't unbolt or remove it unless you have a timing light and know how to use it. :P

no timing light so ill just clean the contacts, ive looked around this forum and google, but i dont know where the CAS :( im planning to go down and get some Contact cleaner tomoz and clean the AFM + New air filter so hope it helps cause im running low on $$$

to get to the coil packs in a rb25de, i have to remove the intake manifold as stated in the link below, unless your talking about a different way :S

wasnt too bad, but if i was to do that, id have to unplug a coil, put it back together and do that for each coil, its alot of work, but as we speak, im cleaning the AFM as it was filthy! really filthy! and changing oil, plus ill add more fuel and octane booster and injector cleaner through

Hell yeah, sounding so much better now :D so far on the car i have changed the oil, cleaned inside the filter box (fair few leaves and foam from off the air intake, was so surprised), new air filter, cleaned the AFM which was bloody filthy, added extra fuel with octane booster and injector cleaner, new fuel filter, new spark plugs, new battery.

So tomorrow ill be taking it to the servo and full tanking it. its currently on 3 quarters and a half. but hoping that little bit more fuel, makes the chugging disappear completely,

If it all works well and the car is fixed, ill be making a donation to SAU, as every detail that came from this site was so helpful! i applaud you all!! :cheers::thanks::thumbsup:

Good to hear the AFM clean helped!

Should also point out - 34 GT's ad GT-T's DO NOT like any form of modifications on factory ECU's - they'll retard the timing and run fat as soon as they detect any increase in airflow.

Other than this, splitfire are a damn good way to go regarding coils - spend the money and get the good stuff, you won't be sorry.

    • @GTSBoy This method was able to get readings of -10 to -2, so it looks like its monitoring.  Now I need to figure out why the vacuum on the line provided isn't alternating with manifold pressure.  I went with 2 lines that an RB25 tuner recommended but I'll get a longer hose and try directly off the back of the manifold.  He may have been used to OEM intake setups while I have a DBW setup that removed the MAF and IACV.  
    • I work at a car detailing and tinting shop called Quark which gets all manner of German cars in usually (mainly due to a contract with Mercedes Benz Kita Osaka, BMW Nishinomiya and others) but every once in a while something special comes in, like a fully restored 1972 HS30 Nissan Fairlady 240ZG... The shop owner had immediately started applying film to the windows as soon as it was in the shop so the interior was completely covered in towels and plastic sheets. But I could get a few photos of the engine bay which was restored like new. Such an amazing car to see in pristine condition in Japan these days.  
    • Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.
    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
