Hey guys i have a r34 25gt and about 1 week ago while driving my engine light came on, so i pulled over and turned off the engine and turned it back on again, it was gone for about 15mins and it came on again, i took the car to this crappy mechanic and they didn't have the computer to analyze the error code. But they told me to reset my computer by taking the battery and if the engine light dosnt come on again everything should be fine, so i did what he said and surely the engine didn't come back on.

But today while driving to work the engine light came back on, but after work i took it for a drive and it didn't come back one....anyone have any ideas what problem this could be?

I called my local nissan dealer and they said their computer is not compatible with imported skylines...is there any mechanic around Sydney that has a computer that can analyze the error codes?

also a quick question i have a semi auto r34 and theres a button with A/T SNOW what is that for?.

cheers

sorting this out is just so simple if you put a teenie bit of effort in - you absolutely don't need Nissan dealer or anyone

you can get the error code in about 2 mins all you need is a piece of wire - I am not going to explain everything as the topic has been covered many times on here (SAU) - what I will recommend is YOU download the R34 Engine Manual - FREE ON NUMEROUS WEBSITES - just google it - then spend all of about 5 mins reading it - it tells you everything you need to know and do

you will probably then work out you have a Code 21 and take all of our words for it that means new coils (Splitfires best) - we all have been thru what you are now experiencing - FIRST just the checklite restart and all appears OK but soon enough if you do nothing one day the car will begin very serious misfiring maybe even to point of not driveable - not good if you are 100s k s from home

believe me you don't need Nisssan dealer or mechanic to fix the problem - so save big money avoiding labour service charges and get to it

Cheers

i wen to get it tested today, came out with error code 21 : main ignition system (something like that), the mechanic reset the computer for me and said if it comes on again come check it again and if its the same error code then its your coilpacks, and on my way home the engine light came on again.

so how long do you guys think i have until it start to mis fire?

mine came on when i was driving home from work, it came up with the engine light, did an engine diagnostic cuz it sounded n drove like a rexi (no offence lol :D )...

replaced all coils with splitfires n been beaut eva since.. no point replacing the bad 1 cuz if 1ns screwing up its more than likely they will all start going...

strange it aint miss firing already tho :laugh:

<br />yeah the car is not shaking or miss firing.... its pretty weird<br />i wanna make sure before spending 700$ to change them <img src="http://www.skylinesaustralia.com/forums/style_emoticons/default/sad.gif" style="vertical-align:middle" emoid=":3some:" border="0" alt="sad.gif" /><br />

its a real nuisance about o.e.m R34 coils but there is no option except pull your coils out and find the duds - my experience was Code 21 randomly appearing first with absolutely no noticeable effect but within less than a 1000k big trouble - it was suddenly so bad it was virtually undriveable luckily I was only about 3 k from home so ran it back anyway on about 4 cylinders as it was early Sunday and no traffic about - not a nice experience - hardly made it back - put in new coils and instant new car feeling!

this is what you need to do.

Take the kick panel off, take the ecu out of the car (undo the 10mm bolt) unplug ecu from harness.

Then plug the ECU back in, when you put it in just tightening up the 10ml bolt is NOT good enough, give the bolt 2 turns then push the plug in on EACH side then repeat this untill the bolt is tight.

Make sure the ECU is pluged in ALL the way and there is no gap. I have seen this happen on countless nissans where people DON"T put the ecu back in properly and they get error codes and engine lights because a sensor does not have a good enough connection.

Try this and let me know how it goes before spending big $$$ on coil packs. Even if it looks like its connected properly, still take it out and put it back in the same i explained.

    • I have been being VERY quiet about what you're alluding to, as it is something that ticks me off... The number of cars from factory that run coil overs is HUGE! Most of them these days do... The other part that annoys me, is people saying "Well all the incabin adjustable suspension is illegal by blah blah blah"... If that's the case, then why can I buy a car brand new that can do it if, FULL STOP in cabin adjustable suspension is illegal...   Also, I could just chuck some aftermarket shocks in my car, throw the stock springs on, after my blue slip, dump my super low springs back in. Same shock and spring style setup... Hell, they could also be the same colour springs etc.     I'm voting, BlueSlipper didn't want to touch the above car for some reason. Whether it be some sort of bias against the car, the owner, them maybe having previously done dodgy shit and now they're being super careful in case they get slapped in the face by the Gumbyment again... Find a new blueslip place.   And can confirm as you had said, yes there are holy bibles of vehicle heights, and all sorts of other suspension stuff. Heck your run of the mill mechanic, and tyre shop has access to all of that stuff. It's how they do wheel alignments...
    • Funny story Heading to Sydney this morning on the HWY there was some slow traffic, so I gave it the beans and midway through my overtaking "power run" I lost all power It seems that I missed a hose clamp,  and the MAF and filter went WiFi To make this more problematic, the little tool kit that lives in the boot, is sitting in the sun room at Goulburn......LOL Luckily for me I found a bit of steel on the side of the road that could be used like a rusty and bent flat head screw driver to tighten it up enough that it got me into Sydney, it is now all tight like a tiger with the aid of a 8mm socket Note to self: Use my brain and double check stuff, and always keep that little tool kit in the car for when I have a brain fart
    • Oh, and as for everyone with their fuel economy changes, I switch between E10 and 98 in the company car. Even do when I had personal cars that could run on E10. You know what changed my fuel economy in any noticeable way? How I drove, and where I drove. Otherwise, say on full tanks of just back and forth from work only (So same trips, same sort of traffic), couldn't notice a difference that I can correlate to the type of fuel in use. In the current vehicle, that's over 42L of USABLE fuel. While 98 is all "more energy dense", it also has higher knock resistance as it takes more energy to get it to ignite too. The longer hydrocarbons, typically more tightly bound. So running the same ignition map, can also produce less power, if there isn't enough time to get it all burnt through properly, as yep, the flame propagation speed is different from lower octane fuel to higher (Higher has a lower flame propagation, due to the more tightly bound and harder to self ignite funs. This is also typically where, a vehicle that is designed purely to run on 91 (Whether it be E10 or normal 91) usually sees absolutely no real world difference in fuel economy for the normal man, woman, or dog.
    • We've got some servos around me that have 91 with E10, 91 (no E10), 95, and 98. At those stations the change from 91 E10 to 91, is typically around 8c/L.   But lets not get started on the price of fuel in Oz. It's ridiculous. All the service stations around me, bar one, the price of fuel has been over the $2 mark per litre for the cheapest, 98 being around $2.45. That one service station is a CostCo, fuel from it comes from the same refineries, and makes no pitstops, it runs great, including the 98. In fact, I've had no issues on CostCo fuel, but plenty of issues at other stations!. The CostCo fuel, was $1.65 roughly this week for 94 with E10. $1.88 for 98. Servos directly across from it, $2.10 for 91 E10, and $2.48 for 98. The part I had to laugh at? If I drive multiple HOURS away from Brisbane, say out near Nanango, or Kingaroy, or even out to Goondiwindi, the price of their fuel, is the same as what it is at the CostCo... Oh, and that BP servo at Goondiwindi is HUGE and goes through epic turnover of fuel, so it's not sitting there for weeks going to shit. And what blows me away, my mate is one of the people who drives the Fuel Tanker all around QLD, delivering to all those places. At the same company his previous role was doing the "local haul" deliveries... Same truck, same driver, same pickup point it all comes from. So you tell me, how the hell it is 60c/L CHEAPER for fuel, when nearly all else is equal, except they require a B-Double to drive half a day out of Brisbane, and half a day back, every second day, compared to the delivery that can be under 30 minutes drive from the fuel pickup point... Not to mention, go five blocks down the road, and Ampol to Ampol will vary 30c/L... And I've had this conversation with my mate... The way it's priced, is just typical, pure and utter rubbish... He also does runs from Brisbane, to all over QLD, down to Newcastle, Sydney, Nowra, Melbourne, Geelong, and even out to parts of the NT depending on the companies needs. His main stuff is all the longer distance away from home for a few days at a time, then when he's back, he loves to just pickup extra shifts wherever he can in whichever truck, hence all the weird different places.   Oh, as for getting E10 into all the fuels in Australia... It was very quickly highlighted, that we don't have enough biomass available to use to make E10 sustainably like they require, and it would dramatically cut into our, and the worlds food chain supply...   I vote we all just start running on liquid methane gas... Plenty of that just getting tapped off at tips from underground decay... (Note, this is pure just stupid commenting. I could very easily highlight the reasons its not a good idea especially on scale...)
    • Am I correct in assuming that the R35's are getting the classic skyline haircut off the odometer?  Quick search on carsales, there are 33 08 and 09 GTR's for sale, only 2 of them have more then 100,000km's on them (116,075 and 110,000 respectively).  And somehow there are about 25 for sale with around 60,000kms? Looks like the classic skyline haircut to me =/
