My car has just started to miss badly, sounds a bit like a WRX and seems to be only running on 5 cylinders.

Car seem to run fine when cold, but after about 15min of driving the miss returns.

As soo as i stopped the car i ripped out the coil packs and checked the risistances. When hot/warm cylinder 3 was giving strange readings, whilst the other 5 cylinders all read 1.3ohm.

Now that all 6 coil packs are cold they are all reading the same resistance????

So how and where much for a full set of new coil packs, whats the go with 2nd hand, someone lend me a spare RB20DET coil pack so i can ensure thats the prob before shelling out money!

Thanks

time to contact Doughboy :)

"oh where are thou Doughboy"... :Oops: Are RB20/25/26 could packs interchangeable????

Cant complain, this is the first problem the car has given me in 4 years, save the speedo cable and alternator :)

Also compression test would be nice.

No way, what i dont know cant hurt me... :) Got to get the car ready to drive down to Melb on the weekend, so if i cant get this sorted may be better of flying down :)

Roy, Did I ever tell you the story about how my car sounded like a WRX ??? Ended up needing a new engine.......

I hope it is not the same problem.

BTW - I think they are the same in all RB series see here for Splitfire replacements:

B-man, if it was every time i turned the key id be worried, but it comes and goes, and always runs fine when car is cold...only happens sometimes when the car has been running around for 15 minutes.

I might just fly down, its cheaper option anyway. Leave the car for 3 months and it may foix itself.

well obviously when the engine has been running for that 15mins or so the engine bay temps are quite high, coil packs do have a failure sympton of which they will deteriorate when hot, and work fine when cold. Relatively speaking this mayb the problem. I think if u are suspect of a coil then get a Coil off a mates car put it on and run the car, see if it is now gone. Easy way to rule out the coil pack in doubt

Im thinkin git is most likely a coil pack, but what is to go with replacing them. Being pedantic im tempted to replace them all, but what isa set worth?

And could be the injectors, as they were installed about 2 days before the problem started, though they had been cleaned, flow tested and spray patterns checked...its posssible the guy that did it wiped them down, put new pintle caps on them and charged me???? But the running fine/bad...hot/cold thing has me thinking coil pack.

    • Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?   
    • Yeah I've spotted this one too, whenever it's lotto superdraw week and I'm browsing car sales dot com for my new ride They must be dreaming, maybe it's worth 150k for the link to Brock?
    • 100% accurate!  We are a pack of know it alls....  But, I bet people go to you when they have a problem! I've been on a bit of a clean up rampage too over the past month!  I've thrown more shit in the bin over the past 2 weeks than I have in the past 3 years combined! Anyway, it's all good fun being different! My wife sometimes does not agree!  
    • ADHD in all form isn't about "can focus, or can't focus" or is hyper active or isn't etc.   It's all a dysregulation. Either time feels to be stationary, or time just vanishes in a split second. We are either under focussed on the task at hand (as we're over focussed on our surroundings) or we have no idea an atomic bomb went off beside us as we're so hyper focussed and locked in on things.   Not to mention the rapid fire thought process. What it takes a "normal" process to think up a solution to a problem, ADHD will be able to give you 5 different ways to solve the problem, and the pros and cons of each. While we can be highly impulsive and lack the ability to "control ourselves" we can also become paralysed with the inability to make a decision for ourselves. While most of us have an OCD like requirement for perfection, we lack the ability often to remain focussed to get things to a perfect state. Those with undiagnosed ADHD as adults, can often find the last part actually stops them ever attempting to do things that they have the ability to do, as the reasoning is often "if I can't do it perfectly, it's not worth doing"   As for projects... Ha ha ha, I still need to take the other half of my wall trim down in the Fiance's office so I can paint it. Need to finish digging and running the back yard drains, my R33, getting the Ninja bike registered (now being sold), the moped project, fixing either of the lawn mowers so they're reliable, along with a myriad of other things.   It's why I've been going through lately and just being brutal and clearing projects off that I won't actually ever complete. IE, moped will go to the tip, or be given away, bike is being sold, Subaru project being sold, some parts for other projects given away. Or I've been making myself focus on one thing at a time, by ticking off the smallest quickest ones first.   There's also a reason by our mid twenties we seem to be "know it alls", as we've all been down some of the weirdest and oddest rabbit holes when you follow the dopamine trail. It's often also why we're more a jack of all trades, but not a master of one.   However, pretty much all of my hobby projects, in one way or another, all come back around to automotive. That's my zen area.
    • Remember reading about this not too long ago. been for sale for a long time  this is like when the wife says you need to sell the car so you put it up for a ridiculous price no one will pay
