Dude,

Don't waste money on a dyno when its probably spark plugs ! When were they changed last ?

You want heat range 5 plugs, gapping them at 0.8 mm overcomes some missing problems

If its not Spark plugs I would go Coils, havn't tried the yellowjacket ones.

yes it sounds like either spark plug or coil pack issue. start with new plugs. if that doesn't help tape up the coils (there is a thread on here about how to do it). if that still doesn't work then it will more than likely be time for new coils.

i wouldn't go heat range 5 plugs. they are too hot and will just cause pinging due to higher cylinder temps. either BCPR6ES or BKR6ES are the 2 options. both will cost about the same and do the same job. ran both types in my 33

I have seen it a couple of times on rb25det engines already. Like you gun it in 2nd gear, 4k, 5k, 6k and it like splutters. You think it should do the usual rev-limiter bounce, but it doesn't. It goes like brrr, like engine is running out of breath with very strange sound. Doesn't sound like the coil-pack misfire.

Anyone had this before ? When you rev it in neutral, nothing strange happens it just rev cuts at late 6k. Any ideas what could it be ?

      I'm so far behind in the jobs I have to do at both work and home (including car) that I have become immortal. There's simply no way that I can die now.

      [HOW-TO] Winter Steam-Clean & Odour Removal in 30 min

      Each to their own I guess  Me, I put just as much time into cleaning inside of the cars as I do on the outside As for getting wet, it is really no different than steam cleaning the carpets at home, apart from the cars carpet dries alot faster than the house, again, I only do it in the hotter months and leave the car opened up for a few hours As I only do it yearly, it is just before I do the diff and gearbox service, so I clean the carpets, then it's up on stands, wheels off, service, clean the undercarriage,  grease the bushings and do a nut and bolt check on everything  Disclaimer: I typically had all the time in the world to kill when I was working 🤣, so spending a full day or 2 cleaning, serving and "looking at stuff" was,  easily achievable, and a fun mental therapy day As for time to kill, I retired last Wednesday, so apart from my physical training, my days are filled with lots of random jobs around the house and garden...."Idle hands are the Devils something something" I am also buying a new house sooner rather than later, I'm actually looking at a potential property tomorrow, I'm looking forward to getting a car hoist as I'm starting to get to old to crawl around under a car, I can only imagine all the undercarriage cleaning and looking at stuff when that gets set up

      Yeah, I'm not interested in wetting the carpets, and I don't care about brown dirt/dust that lives deep in the pile or underneath. It's not like I crawl around on them in my birthday suit or eat dropped food off them (because there is never any open food in my car). The seats are alcantara (cheap Chinese imitation alcantara, to be sure!) with barely 1" of foam pad behind the surface. That's not getting wet either. Any car that I would be happy to get the interior wet, I would not care to put the effort into.

      We have one that holds 2.8L of water. On floor carpet that hasn't been touched in 2 or 3 years, will take a minimum of 2 fills of the tank to do a bedroom, and that's going AROUND the bed.   In the cruiser, I used an ENTIRE 2.8L tank, just on the front passenger footwell. But it had some fungus growing, and had been full of mud from being used as a 4WD for many years. I can do that floor again, and it will still pull mud out. However, the water now only looks dirty, not pitch black and leaving full sludge in the bottom of the tank it sucks back into. Oh, and, this is about a $1500 unit.
