Hey everyone, i know this is going a few pages back... but regarding coil packs and issues with them; Mine on my R34GTT seem to have started playing up (shaking, mainly noticeable on idle) and car has far less power than normal.

This happened to my previous R34GT and i replaced the whole lot with Yellowjackets, this fixed the problem.

I've ordered some replacements but my main concern is if i'm doing any damage to the car by driving it around before i receive/install the replacements.

Because i know there's a problem i am driving it like a nancy boy as i'm worried i'll screw something up.

I'm assuming that your first port of call was changing spark plugs?

If the coilpacks are on their way out, and they are bad enough that its not idling right, it will def be missing on boost and you'll hear a bunch of misfires through the exhaust.

I'd change plugs to a $25 set of Copper plugs and see if the problem persists, before spending $$$ on new coilpacks.

What mods? and what plugs are in it atm?

Thanks for the reply mate,

Have changed the spark plugs with no avail (problem persisted), definitely missing on boost but once i noticed something wasn't right i didn't really want to push the car too hard.

Only modification is adjustable coilovers, apart from that it's completely stock. Plugs are factory at the moment.

I'm fairly certain it's the coil packs as it feels exactly the same as my last car's issues

Hard luck Tony. I know how much time you put into that over the last few months! I'm waiting for someone to steal my car (secretly wishing)...seems only to happen to the people who don't want theirs stolen :/

On the brighter side, you can upgrade your daily earlier than expected...

Sorry to hear man :(

all it needs is tyre level with guards front and rear and will be perfect :)

how much low will I get from eibach springs? I would like to drop it only like an inch on the stock coilovers... want this one to be legal as possible

this... oh god this!

Pulled carb apart and got busy with the carby cleaner

Fixed the out of tune jettings

Replaced the ridiculously restrictive air filter with just mesh

Idle's now more stable

Throttle response improved greatly

Sound is now even louder/better

Might aswell service it too while it's stripped

Don't think neighbors seem happy though apparently 15k+rpm at 11.30pm is breaking some law

the smackdown... embrace it

Hey Scott's gonna be making a 3.5" dump an front pipe(2 piece) for around the same price of all the other combos.. Would you be interested? Coz then that's 3 of us

dunno man... I was planningn to buy second hand so it's cheap and doensn't have ANY shine to it

Don't go too low, evo handles great from stock, so any lowering is purely cosmetic / anti-4wd jokes.

An inch is about perfect isn't it? What wheels are on it?

yeah, that's what i'm after... about 1"

rims are KOYA RG Tech (Advan RG ripoff's) 18x9.5 but unsure of affset untill i take one off... looks to be approx +20

    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
    • Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.
    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
