Help, getting fed up now :(

Hi all, keep getting small issues that are winding me right up I've had missfire after missfire, replaced the coilpack loom resoldered the mafs replaced the ignition amp and found a boost pipe off in the last few months all problems that have given me the dreaded missfire.
Yesterday she was running lovely, went out for my Father's Day lunch in the forest and I was feeling so happy with the car.

On the way home after a nice long drive It started missing when under boost but was completely fine when driven off boost. It was a super warm day as well, would my plugs cause this or are coilpacks my next step.

checked the ECU plug? Make sure it's done up nice and tight

The last time I had this issue, I had a split in the hose going from the intercooler into the twin turbo pipe! Wasn't noticeable until my finger went into it (hoho!) - the split was underneath and slightly to the side. I bought new coilpacks only to find out it was a £20 hose!

I might have an old set of coilpacks I left in my parents garage from my previous GTR, if I find them you can have them, might be worth a try before shelling out unnecessarily!

Have you driven the car now it has cooled down? Does it still do it? Might be worth whipping off the coilpack cover, it does get hot in there, won't help if your coilpacks are a bit temperamental!

I haven't driven it since but will have a go shortly, thank you for the kind offer of trying your old coil packs that's a very gentlemanly jestjure. My first boost missfire was due to the vac pipe coming off the fpr so first thing I will do is take it for a drive and see what happens.

My coilpacks are standard and old btw that's why I can't rule them out yet,

It sounds like you have another boost leak, assuming the first was caused by a damaged hose it may be a good idea to replace all the hoses as these cars are now getting on a bit

If it is your coil packs what ever you do don't buy the Chinese ones. Go genuine or Splitfire.

Replace all of them otherwise you will be continually chasing the weakest link

I won't, I will probably go genuine anyway.

This jubilee clips looking like the problem, fingers crossed

Good news I have replaced the jubilee clip and all is lovely once again, been for a long drive and we are issue free. I think I'm pretty sure I know why it failed as well..

After the first time this one clip came off and the car ran like crap, I stupidly tightened it with my impact gun with an 8mm bit fitted. Thinking it was nice and tight what I failed to realise was that the four small spot welds had actually broken on the clip. Then a good drive Sunday obviously worked it loose.

It's amazing how much even a small boost leak effects these things it's quite shocking !!

Anyway thanks for all the advise and red duke for the offer of parts to help...
this is a lovely helpful forum

No problem matey I can recommend the Mikalor / T-bolt clamps, great even pressure and don't strip the threads like the older jubilee clips! Glad you got it sorted, worst feeling on the world is a poorly Skyline, it's usually expensive!

Balls, seems that when she's used for a longer period and gets really warm this missfire is back again only on boost other then that she's lovely , plugs and coilpacks next I guess...

Coil packs breaking down. Very common remember they could potentially be over 25 years old.

Go igniterless - one less thing to worry about.

I'm pretty sure it will be the coilpacks especially if they are original, had the same issue on mine, went with splitfires not a problem since
