:D i have a problem where my car drops a cylinder intermittently it brings up engine check light .i have checked error code which is 21,and found it to be no cosecutive ignition signal while engine is running i presume this would be coil pack as my transistors are built into each and every one of my coil packs unlike earlier skylines where the had a transistor module mounted at back of engine on top of the plastic cover, but it only has happened three times and it doesnt do it long enough for me to disconnect each coil to pin point the bad coil,my biggest problem is the cost of the coils i have being qouted aprox. $2-300 a coil due to the fact that the transistor is built int the coil also depends on which coil type i have as nissan list a few part no.s does anyone no which coil part no is mine.my skyline is r34 GT with a rb20de engine or if any one no of a cheaper option in new zealand as prices for these coils are all over show the other thing i am wondering is it possibly because i have reset the computer and it always does it secound drive after reseting the computer is this possibly a phenomenen that happen with computer relearn or just a coincedence.can anyone answer this.

My engine light came and and I got a service they hooked up the Nissan computer but they couldn't find the problem. I rang Power Road car sales where i bought my R34 Gt from and they identified the problem by just me explaining it over the phone.

I just got a new coil pack installed by them today, costing 240, (130 for the coil pack form Nissan) They also claim to have a machine that tells them which coil pack is playing up.The car runs smooth now, but my engine light is still on. I was told that the computer needs resetting, but I would have thought that the light would switch its self off once the problem is solved.

Does any one know how to reset computer or do i need to take the car to a specialist?

Disconnect the negative terminal from the battery, hold your foot on the brake for around 10-15 seconds, reconnect it, and voila.

Never replace with OEM Nissan coil-packs....they're the reason why you're in this situation. Get splitfires and never look back. Just replacing one coil means you'll get another do the same thing very soon, in the end all 6 *will* die and you've spent a billion dollars installing a replacement pack at a time.

Do it right the first time, splitfires! :dry:

Slightly off topic - $130 per coil pack from a Nissan dealership that's not too shabby, my local Nissan dealership was asking me $196 each.... so I ended up getting a set of splitfires for $530 - to be honest I can't feel any difference (I have an r34 n/a btw) - splitfires are great value in comparison to the Nissan ones.

Splitfires in the end will save you alot of money, not every mod is going to give you a big difference. I felt good response after installing them :dry:.

But anyways. These kinda mods are more durability.

Atleast thats my opinion on this particular mod.

Speaking from experience, once packs start palying up the car runs like shit, you lose power and get missing high in the rev range under boost, and that's if you haven't already lost cylinders. It's all down hill after they go.

My advice to anyone that buys an R34 is "factor coil-packs in the price and do them straight away"

yeah you were all right. The next day the car went to shit.. They are all replaced now and the engine light is off and running smooth!

Thanx for your help..

I hope any one with this problem in the future doesnt make the same mistake.. replace them all !

Looks like I have the same problem. But I also get the TCS OFF and SLIP lights on aswell as the check engine light. Did you have those come on aswell??

    • Given you're running a 2.8 and my 2.5 is not really like for like, I suspect there could be a bit more timing you could give it. What is the kW yield per degree you're putting through it? Here's my E85 map to give you an idea, where it was I could still get another 3~4kW per degree thrown at it.  
    • It turns out that Setrab make a fan specifically for the oil cooler which is great and I've installed it with minimal swearing. I removed my 2x 12in push fans from the front of my aircon condenser and wired them into this. My main thermo fans kick on when I use the aircon anyway and would effectively already be working as puller fans through the condensor which is infront of the rad. The push fans (understandably) didn't really do much in the config they were previously in so now they're out. Now we're on to the "Oil fan doesn't really do much either!". Yes I'll duct it next if it does nothing in heavy use which it shouldn't. But hey, the object exists and fits great and is cool. Let me have this. The car is still in the "do my fittings leak oil now? do my wheels actually rub?" phase. I did a spirited drive on them and didn't hear or feel anything. Then I got back home and noticed there were grind marks on the inside of the rims, though I couldn't see where they were touching I got out the grinder and attacked the suspects. Note: I do not know how to use a grinder. Then I realised I had dragged my new rims across my concrete driveway before I did this drive. I didn't think I had damage at that time when I briefly looked...... but remembered this occurred after I did all the angle grinding. The grinding on the wheels in some very specific spots. It's not around the whole rim for example, which lines up with dragging it across concrete more than hitting a suspension component for even 1 full rotation. So everything is currently painted and taped up and I need to test it some more to see if it really IS rubbing, but from inside the car it doesn't feel like it is. In other news I attempted to do a before and after comparison of the heads/cam upgrade thing. Dynos lie, everything is in different measurements. Here is the data from the sandown back straight. Car go faster than before. Vroom vroom.
    • Here's my base ignition. +3 correction to redline when shooting water/meth which is always on. Looking at my old ignition table, I should be able to add 1-2 degree's next time I'm on the dyno.  Let me know your thoughts. 
    • Given what I know now - same haha, but this was 12 years ago with second hand 740cc Nismo injectors in my S15 daily, I was too busy hunting elsewhere for the issue to even look at the injectors, running through some cleaner was a happy coincidence haha
    • Not a terrible idea. But if I ever had concerns that my injectors were sufficiently dirty to be causing me a problem, they would be out of the engine and onto the actual injector cleaner/testing bench.
