hey guys,

im having a bit of trouble understanding my r34 gt auto. my malfunction indicator light keeps popping up on my dash randomly. mostly when i just start my car. i took it to get the computer scanned and alls they could tell me is that there was a code 21 in the computer which they had no idea what it was. im really worried that it is going to cause more problems in the future. does anyone have any idea what code 21 is. they deleted it off my computer but the light is still popping up. as far as i can tell my car is still driving pretty good. it takes it's time changing gears sometimes but it has always done that being an auto. would love some feedback!!!!!!!!!!!!!!!!!!!!!!!

CARLY :ermm:

yer well it has only just started to misfire which sux! i have been told that i should wait until it gets a bit worse so they can locate which coil is on its way out.... hopefully not all of them!!!!!!!!!! it is starting to feel a bit shit when i drive and yes actually i have noticed the noise from my car is a hell of a lot louder in the last few days. do any of you guys know round about how much they would cost? is it something you can fix at home rather then having to spend a lot to get it done through the mechanics?

Get splitfires, do it at home in an arvo.

Don't replace factory Nissan coils one by one with factory Nissan coils, they're all going to die prematurely and it's not worth the headache.

Put the splitfires in, then smile to yourself knowing you will NEVER have an issue again

i agree with Dan there, i did that, replaced 2 coilpacks with stock nissan ones (which at the time were worth about 180 each) and then when the 3rd one went i got the splitfires and i am glad i did. so take some good advice and go with the splitfires, they arte a lot cheaper now from when i had to get them

:P

splitfire coilpacks are between 500 and 600 depending where you order them from and how much delivery is. there are also rip off ones but im not sure how they rate, have read that they're ok for budget coilpacks, but some people on sau are really against them.

its an easy job to change them. i used the following tut to get to my spark plugs

pay particular attention to step 5, its very important to get that exactly right :P

i have the same problem on my gtt, will eventually save up to get coilpacks which will hopefully fix other random noises when the car is idling. i guess i'll get a constant miss soon enough to hurry me up tho lol

i priced the splitfire coil packs but im a bit broke atm. is there a second brand any of use would recommend a little cheaper? see this is the bad thing about imports!!!! as good as they are :)

i priced the splitfire coil packs but im a bit broke atm.

lol, same problem as mine. stock coilpacks only last like 120000kms so its def worth replacing them all. look at import sites like justjap

http://justjap.com/store/search.php?mode=search&page=1

there's no doubt other sites and other types of coilpacks. these may not last long tho, splitfires are the most praised coilpacks

my car absolutely sharted itself today!!!!!!!!!!! i had just started my car and seriously the whole thing was shaking! sounded like i had a massive turbo but sadly no my bf says my coils must have completely died...... not something i wanted to hear. t'ville is a bitch to get coils but i ended up getting a 6pk online. i went for yellowjacket cause they seemed pretty good. sorry i couldnt go for the splitfire ones dudes lol really would have liked to but im only part time and since it was spire the moment i just got what was there. hopefully that fixes the ignition light in my car. so sick of the reminder!!!!!!!!!!!!!! shall keep u posted :banana:

yes, please do. i'll be looking at some yellow jackets soon. birds was saying good things about them in the oil topic (at least i think it was the oil topic). they're probably about as good as the splitfires, but if worse comes to worse and they last only half as long as the nissan coilpacks, thats still ~60000km :banana:

lol well their website seems pretty good. it shows the colour of the spark compared to another and it is super bright. i think i payed $400 plus $20 postage. they are based in NSW and they said it would take 3 days so i cant wait because i wont drive my car until they come! ..... so shame having to drive my dads falcon!!!!!! so ugly. yellowjacks should be fine. im only planning on having my car for another 4-5 years before family come into the picture so at least it wont be my problem if they do go again. :yes:

has just ran into a big problem!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :thumbsup: my bf told me he knew how to put in the coil pack but now after looking at it he has no idea!!!!!! do any of use know where i could get some kind of step by step instructions????????????? i have had a look on the forums but nothing for what i need. biggest problem being until i find instructions i cant drive my baby. so whoever can help me out i will love you forever lol :thumbsup: <-- thats just awesome

my bf told me he knew how to put in the coil pack but now after looking at it he has no idea!!!!!!

Your bf skills are a lie!!!! :thumbsup:

LOL I just wrote the whole thing and realised you've got an n/a :S They're nice and quick!!!!

OK parts that are essential to remove are-

The engine cover (4 bolts)

Remove the twin entry manifold that crosses over the engine (couple of bolts, be careful of the thin metal gasket)

Remove the PCV pipe that crosses the cover

undo the allen key screws, then take off the cover to get access to the packs

Edited by 666DAN

its really straight forward, just takes a little bit of time the first time (tho mine's a turbo).

follow these, give yourself an hour or so and enjoy!

more bad news guys!!!! :domokun: mine is the neo motor and it seems a lot different than what use have given me but thanks a bunch for helping me out. think i wil just have to bite the bullet and go to my mechanic. i asked him today how much it would cost and he said about $80 which is pretty good. would have liked to pay nothing though lol if use knew where i could find the neo version of what use found that would be great but otherwise i dont think i have any other choice lol

search the diy topics if you really want, but its exactly the same principle. i have a gtt, so neo turbo.

take off the engine cover, then intake piping, then undo the screw holing wires onto the long bit of plastic in the middle of the engine, then undo the bolts on that bit of plastic, then you can see the 6 coilpacks, unplug them carefully and replace. it is really straightforward, and seeing as the car isn't on the road just go out and have a play with the socket set, it is really really easy.

btw throw some new plugs in while you're in there, probably just go bkr6e's if you're stock, or whatever the repco guy suggests, if you replace them regularly then there's no problem with coppers, if you want to spend the money go platinums or iridiums from ngk, or for only ~$40 get 6 bosch platinums, its what im gonna do next, the code is FR7DPX for the bosch's

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
