To be fair......Yellowjackets have their place. It's just that it's the bin!

I use the pedestal vice in my shed, but anything will do it, then squeeze a feeler gauge in and see how you go. Basic feeler gauges are cheap, tools are minimal, so no excuses. And learn as you go..

i got a reply from the guy on ebay that sold me that coilpacks:

The coils are brand new too though.
You need to confirm there are no other underlying issues with the car, such as:

- Ensure that the coils are mounted and plugged in properly and the rubber boots are seated correctly and the springs are making good contact with the spark plugs. (This is the most common cause for a misfiring coil pack).
- Check that the coil wiring loom isn’t old and brittle or faulty.
- Check the CAS (Crank Angle Sensor) as it may be faulty.
- Check the TPS (Throttle Position Sensor) as it may be faulty.
- Check the AFM (Air Flow Meter) / MAF (Mass Air Flow) meter as it may be faulty.
- Even the ECU settings may affect how the coils operate. Please ensure the ECU you are using does not need to be retuned or reset to accommodate the new coil packs.

now i know the coil packs are definitely on properly,wiring loom is good, but not sure on the other things but i would assume that would of been checked over while tuning.

So what do i say in reply ?

Well, this is why your chances of getting a refund on these coils is a bit slim. The term is "caveat emptor". Not doing your research on the suitability of a product before buying it is a mistake. When the product gets installed into a system where the product itself could be faulty, or any of a dozen other things could be faulty, then convincing the seller that the product is at fault is a difficult task.

We all pretty much know that they are going to be at fault, regardless of the possibility of other causes. You either run through and do every one of the checks that that seller asks you to, and then tell him the results, or you tell him a porky, say that you have done the tests, and have even swapped out the coils with a friend's Splitfires/new OEM coils and it runs properly with the other coils in it. The end result of doing the former is that you might still not convince him or yourself. The end result of telling the fib is that you might get him to agree to take the coils back and all will be right with the world.

If bought on ebay my advice is to test with a known working set of coils and if the issue goes away let him know, if he does not play ball, start a ebay/paypal dispute....when that fails go to consumer affairs.

Once consumer affairs gets involved he will have a headache at hand, 9 out of 10 times they side with the consumer.

I know because i had a customer buy a Exedy clutch kit, he dropped the clutch cover while fitting it onto the ground (bent corner of pressure plate cover with concrete dust still on it) and consumer affairs still said its my problem...eventually exedy agreed to take it back stating that from experience consumer affairs generally finds against the supplier and manufacturer regardless and its not worth their tech team and my time attending mediation meetings, and they already have washed into the price for these things to happen.

i think my best bet is to email trent and ask for some help if he's got time.im sure all of that stuff would of been checked while tuning ?

if i had other coils to try i would do it right now and im 99% positive there would be no misfire.

tomorrow i'll be taking out the plugs and ill take it to someone to gap them properly for me and see what happens

gap them yourself bruh!

if they're copper, just slot in a feeler gauge and tap the tip with a small meta object..

I'm a lazy prick, so I just bang mine against the radiator support.. works a treat.

alright alright lol i'll get a feeler gauge tomorrow. i guess its something i do need to learn for myself :P

its extremely easy mate, and a good tool to have. You need to check each plug when buying new, as always 2/6 plugs i have bought have been out by a least .5-1.0

      Shift Performance Ganador Reps

      By Lmic · Posted

      Came across these Ganador reps and am wondering if anyone has used these/come across these ?  Seem to look like reasonably good replicas (shape wise) from what I can see. Ive been told by them that they are moulded to be exact copies of original Ganadors (but thats what every replica version will say) https://www.shiftperformance.com.au/ganador-style-mirrors-suits-nissan-skyline-r33-gtr Photos of them installed appreciated Thanks 👍

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      lol, yeah, and how gutted I am now I’m back over in Europe (actual Europe) and dealing with the nightmare of U.K.-Continental Europe bureaucracy.   Anyway, arrived in NL early January with the BMW, whilst the Skyline followed suit about a week later. Both cars ended up stuck with their relative importers for about six weeks. Since then, I made a trip to the Nurburgring with a friend and have since ditched the Skyline in the garage. This week, I finally managed to find a suitable shop to do an alignment so hopped on over to Germany to fix the miserable mess the local Netherlands shop conducted; the car was just not aggressive enough in the rear for my driving style - I found myself understeering a fair bit at the ring which was really a first for me with this car. Mis-matched F&R tyres can be held partly responsible - have now moved to F+R NS2Rs. One thing I’ve noticed is the 180kph limiter just does not cut it here. I quickly hit that (for the first time) in Germany on the autobahn. Japanese circuits are small - at least the ones that were near me. I rarely spent much time in 4th. After much deliberation with the HKS SLD, I have ordered Nistune from Matt. Whilst the Skyline has been gathering dust I got to learning the highly neglected BMW I bought in the U.K. was in fact just that, highly neglected. Took the ol’ dog down to Switzerland last weekend with a progressively deteriorating front end. It went from vibration during braking at highway speed on the way down, to vibrating non-stop on the way back. I’ve already fixed numerous engine issues - low oil pressure, f**ked injectors, incorrect coils and plugs, electric water pump. Still to do is a suspension and brake overhaul, rear subframe replacement and likely more ageing engine electrical components. But I must say, I love it. After so long with the Skyline, I really didn’t know cars could be so comfortable.
