Hi Guys

last week i noticed this for the first time, i drove from Newcastle to Port, went through some hills and my car started to splutter and loose power now this was new to me as it wasn't a missfire as such but more of a sruggle to make power then die.

i have worked at Port all week and the car has been fine, not a drama. i gave it a boot afew times and nothing. Now last night i drove to Coffs and it was fine but today i was giving it a little and about 15mins latter it spluttered and died in the middle of a round a bout mind you lol.

It seems to happen when the car is hot, could this be spark plugs/coil packs? at first i thought fuel pump but it's been fine all week.

it's really wierd.

Mods: front mount

3.5inch exaust

Standard turbo

Boost controller running 10psi

coil packs are stock but siliconed

i pulled the plugs out thisarvo and they have the usual blackness and coil packs look okay.

Any ideas?

Cheers

Cam

ok, if it is the CAS will this slowly get worse? can this be easy tested to see if it is? and how much roughly to fix?

at this stage with work i don't have the time to fix but need my car, if it's easy to do yourself i will do it.

i drove it today for about 5mins just to see if it would go, it seems to be when it gets hot it does it

cheers for the help guy

well the known baddie you have is the taped/botched coilpacks

you already know these were causing an issue last time as you have repaired them

so the most likely culprit is the coilpacks - i can't understand how the CAS is at fault, unless it has come loose

how often does a CAS fail? i cant recall a single CAS Failure? it seems in the last two weeks everyone posts "CAS" is at fault. check the basics. check your coilpacks, check base timing at idle (that would confirm if CAS is toast or not)

If it died in the middle of the round a bout then i'd say CAS.

Won't be coil packs.

CAS's play up in some fken weird ways. Car can be fine for a week and randomly die, and then it might die twice in the next hour and then be fine again for another week.

My CAS when it was failing did exactly that - made it a bastard to diagnose

Ahuh...cheers..i always figured it was a sensor of some sort causing it, it only really happens when cars been undriven for a while, if i give it a bit of a flogging it always corrected itself...

So what would be wrong with it, or does it just need replacing?

Hi guys, thought I would let you know the diagnosis of my problem. Turns out it was a faulty airflow meter, yep the symptoms matched what you guys were saying about the Cas had it looked at didn't find nothing, when it did it again we put the computer on it and yay. So take note the airflow meter can cause similar issues, and after a new set of coil packs, plugs, I even got a cas. thank god we got there

    • Haha luckily we don't have emissions, inspections, or any laws against power adders here. They only thing they somewhat keep an eye out for are ridiculously loud exhausts. 
    • Just wanted to pop in an update on my setup. The CD swap has been great, I love the mazworks housing for the overall simplicity. I ended up sealing my trans tunnel with a thin sheet of aluminum reused some of the holes on the trans tunnel, and laid some window sealing EPS foam around the edges. Works great, really quieted things down and sealed up the car.  As for the power comment. Right now I am also running about 650whp. with the way the bell housing is attached to the face of the transmission I have zero doubts it would be fine, mainly because the input shaft and main shaft bearings are seated into the bell housing adapter. This means the load is NOT on the bolts to maintain the power, rather into he casing of the bell housing; Yes the bolts are doing some work there, but with both shafts locked in zero worries.  End of the day, the Mazworks solution is the easiest and safest. no need to take your trans to a shop to get milled perfectly, it fits with minimal clearancing, and you can use all your existing clutch and flywheel.  Driving wise the CD has been great compared to the big box, I'll probably swap my final drive at some point. The serial 9 shifter is gooooood, my only qualm is how tight it is, it takes a fair bit to get use to, 5th and 6th are a bit eh/hard to find at times, but maybe I need re-adjusting, and I think my clutch master is very tired and needs a rebuild. 
    • If you are keen, have a look at my build thread. Car is for sale for the right money or straight swap for a F80 M3 LCI.
    • Welcome mate.  No point in over thinking it, buying any one of those cars you mentioned is not a smart or logical choice with the availability of many "better" (re price to performance) cars available to you.  The heart wants what the heart wants, buy whatever it leads you too.
    • Hey everyone! Im so grateful to be apart of this community and ill do my best to be apart of this. Firstly, i'm not disclosing my real name due to in real life circumstances surrounding my privacy and public image (sorry lol) Secondly, The only thing personal I am willing to share is that I'm from Sydney and a descendant of one of Sydneys largest mortgage firms. I got gifted my first ever car, a 2022 Porsche Cayenne and I love it to death. Ive been driving it for about 5 or 6 months now and honestly Im so grateful for my parents for gifting me this vehicle. However recently I've been working my ass off to afford my second car (which I need help deciding soooooo community help me out please?). Once decided, im planning to try modify it myself. Recent I've been thinking about getting a Skyline, particularly a 25GT or GT-V, yes I know overrated as hell, but I'm also considering a Chaser which I recently came to love. However my dream is to one day own a 180SX (So hard to find clean versions and im not really into importing).  Lastly before I send this off, I want to apologize if I sound tacky or pretentious. I try not to and want to genuinely learn from everyone and anyone. (Im no expert in this area) Thanks for reading!
