Plugs or coilpacks. Pretty common with RB's, or the old fuel pump is getting tired. Replace your plugs first, then look at the coilpacks & fuel pump. I've got a spare set of RB pack's if you get stuck dude.

Pretty much plugs or coil packs. If it doesnt have an aftermarket pump, check that as well. Otherwise, it could intercooler piping, I've just fixed that problem in my car. Check them all in that order, because new plugs would be beneficial whether they are causing the problem or not.

man i've had 2 missfire issues with my rb20 over the last couple years... whenever you mention a missfire on here you get a million people saying coilpacks.... and while it is a somewhat common problem with skylines, it was never the solution for me and it's not necessarily the solution for you.

my guess would be your crank angle sensor.. sounds very similar to when mine had problems..

but it's just that, a guess... could be a variety of things... best bet is take it to a garage that knows skylines and get them to tell you what the problem is.. will cost about 100 tops to find out what it is.. which is cheaper than trying 5 different things to fix it.

      @Kinkstaah yeah I initially checked with Chequered as I've used them with a previous car. But they have stopped sourcing and installing Nistune chips. They only do tuning now. I did not want to pull out my ECU and send it away somewhere to have the chip installed. That would mean no driving the Skyline

      Should have checked that.  On the plus side, I got my Bluetooth adaptor.

      Each province differs a bit but we only do mandatory vehicle inspections here for heavy vehicles (Think Ford F350 and up). Those inspections are done by mechanics that are approved by the government. Besides that, it's a free for all as long as the car looks stock.  I asked because I love seeing how engineering differs from country to country. Here in Canada, all designs must be stamped and signed before they can be brought to fruition. (I.E Bridges, structures, Electrical panels, machines, literally everything shy of a wooden table) This can only be done by a professional engineer or professional engineering technologist. Both are protected titles, but the latter having more of a limited scope in what they can stamp. To become a professional engineer, you must complete a 4-5 year bachelors degree in your field of engineering, be part of an engineering order and undergo 4 years of apprenticeship, testing and mandatory continues education. Same story for engineering technologists, but a 3 year associates degree in some form of engineering technology will suffice. If you do not comply, or pretend you're an engineer or technologist, off to jail you go. If you stamp a design that fails, off to jail you go. If you stamp a design that fails and kills someone (I.E Bridge collapse) Off to jail you go for a very long time, your family will be ridiculed on the news, neighbours will surround your home with pitch forks and your dog will disown you.  Same for specialised trades... Example Electricians must undergo 1.5 years of post high school education, 4 years of apprenticeship, testing and hold proper licences. It's for the best, but then we also wonder why we're so short on engineers and tradesmen haha. We also have professional engineers who were only school smart but have no idea how a drill works. They generally go straight into management roles out of school which is also for the best.

      I have a friend who has used Chequered Tuning and CMS. Went to CMS when Chequered had a long wait time which is kind of the norm (for good reason). Was very happy - I'm pretty sure the very simple thing you're asking will be simple.
