Gday Again, Still Chasing Issues With My Wgnc34

[lilcrash]

ok coil packs are finally on there way, i bit the bullet and conned my parentals into buying them for me.

retracted - it is a wgnc34 thus rs4s yay for me (just out of curiosity, is there a way to tell what sort of stagea mine is?? what are the diffrences between rs4/rs4s etc..)

RS4s is a factory manual

thats why i thought it was possibly r+r, and what i originally thought was a miss feels more like its stuck at certain rpms and is struggling to rev harder. so im guessing this is the "wall" that its hitting as mentioned earlier. kinda feels like revlimiter but a quicker space between bursts, for eg. rev limiter is like this rev..............rev.............rev.............rev, but this is like rev...rev...rev...rev.

so yer. im lost

Hi

This rev...rev...rev...rev sounds very similer to what i had a while back. It would hit at about 4000 rpm it turned out to be the fuel pump. One sard fuel pump and a fuel presure regulator an all is well againe. I would still go with the new coil packs as these will be a good investment if you intend to up the doost in the future.

cheers

oh phil, now you have really confused things, he is sure to get the Corolla now

So in summary, 5 for coils, 4 for R&R and 1 for fuel pump.

I don't know if it is coils? how can you diagnose symptoms without testing? All anybody can offer is speculation, now that you have bought new coils I really hope it doe's solve your problem, cause if you were considering an insurance job before this might put you over the edge. Good luck with it. I gotta go insulate the wirring on my coil pack harness with silicone as nissan wrapped it with insulation tape (dodgey buggers)

phil, i think i may have to be against the fuel pump thing im sorry. its just that the problem goes away with the new spark plugs every time. but lately it only misses if i boot it after cruising for a while.

and chook if i was to get a toyota it wouldnt be a corolla. rather a jzx90 chaser.

i was kinda getting to the point where i wanted to make a deal with some one who is only upgrading coils for performance purposes. like borrow there coils for a day test or what ever.

thanks for the help everyone. after christmas i will know if the coils work.

well, fixes:

install a better fuel pump, such as a 040 Bosch, or gtr fuel pump

if not interested in outlaying cash then at the least wire the fuel pump to a direct battery feed, to get more voltage (13.8v)

a 2ndhand gtr fuel pump isnt expensive anyways.

build a air:fuel ratio kit from jaycar and install and tune, or find a 2nd hand safc II off ebay. search to minimise the cost.

use ngk BCPR6E copper .8mm vgruve plugs, under $20 for the 6. money definately not wasted, good for 20,000kms+ and 300rwkw

grab the selleys 401 hitemp industrial silicone sealant, and a corking gun from bunnings ($15 the lot), and go nuts on the coilpacks.

there will be plenty of sealant left for the toolbox so it isnt money wasted (lasts yrs).

with the new sparkies, the coilpacks sealed to stop wasted spark, and a better fuel pump with directwire battery feed to deliver max output, put the car on the dyno and tune the air:fuel ratio. adjust the timing slightly, and you'll gain power whilst providing better fuel economy, and it should hit the nail on the head as far as R&R or wasted spark goes.

my guess, $200 for the parts above all up plus a dynotune

money isnt the problem. my missus will kill me if i buy something i dont need is all.

sorry to be so late into this problem from my experience . I have found after weeks & weeks of sorting under boost & under standard boost i did have a break in the wiring loom for th coils . have been running up to the boost cut in an s2 for 25000 kms and have had no dramas . still run this boost now and looking at running more with a greddy profec b . good luck hope it works out for you soon .

if you want to have a mess like that good luck ,nice simple

then spray what colour you like ,there is few topic`s on coilpack`s & i have also posted on them ,but make sure you clean then well very well tape up connector`s & rubber cover, i did mine 18 month`s ago & still sweet + i have found easy way to tell if it is coilpack`s ,PUT AC on FULL & if you get miss then you know what you are LOOKING for .cheer`s chuckie.

ok everyone, problem solved, it was the intercooler. put in the just jap stealth kit and now ive got 10psi all day and no miss.

[Jezboosted]

good to hear you got it sorted lilcrash. pics of the stealth cooler fitted ? i am going to buy one soon, so the more i can see on S2 stagea's the better

[lilcrash]

the only issue i found is none of the bolt holes line up very well,( the 2 bottom ones are close enough that you can bolt them, but the top one and the one on the longer pipe is no where near the holes, i used the supplied zip ties to hold it for now until i can get new mounts put on) and it sits on a weird angle, i bent my mounts to lift it away from the road and level it.

that was exactly the same issue I have with my stealth cooler that the bolt holes don't match up (I got the top bolt hole to match but the bottom ones are slightly off)...I've just gotta make some time to make up a piece of steel that bolts to the two bottom mounts and then use one of the remaining L brackets I have to bolt it up to the middle (the center vertical bar where the horn and top mount of the cooler is)...and also fix my miss (new plugs) and investigate what sounds like an almighty air leak

[lachlanw]

tape has worked twice for me . one guy didnt even notice his car was missing . it was 100% the token miss . run clean get to 4.5k pop pop pop then pull hard rest of the way through . will buy split fires if my car ever needs coils . mine are mint atm

[loymclure]

Greddy emanage Ultimate (im bias lol, but any after market ecu will do) chuck it on the dyno get it retuned for your mods.... presto problem solved. People waist alot of time and money and tempory fixes but something i have learned with my car is any mod you do to enhance performace (+- fuel, air, timing) while using the stock ECU will often cause you grief unless retuned properly.

I stress this is only my opinion and will probly have alot of people who disagree!

yer just a quick update, ITS BACK . . . . . . . . . dun dun dun (evil music)

brilliant chuckie - thanks for that adaption of an idea I'm gonna take a look around for that spray silicone.

It's gonna be your coilpacks mate... I had exactly the same issue once i raised the boost to 10psi.. Car was missing badly around 4500rpm then would slowly clear up... changed the coil packs to spitfires and now pulls hard all the way through to redline..

[lilcrash]

ive had the miss since i bought the car(it was stuck on 3psi, the intercooler put it back to the stock 10psi) so boost isnt the problem, but yer im going to assume its coil packs. hopefully when i get my check from just cars il get some splitfires(even though i should replace me rims so i dont have to keep reinflating them), i should have just got my parents to get them like they were going to, i only told them to get the cooler because i had a huge boost leak.
