Problem With R33 Gts-t

[Cam84]

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

most likely coilpacks. possible cas

[Cam84]

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)

[Adriano]

Ive had a cas fail. check your trouble codes, sounds like igniter (unless its a series 2), or cas.

Thanks for the help guys

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

I have this problem occasionly.It stopped for about a year, then started doin it again.What is a CAS??

[BOOZTJUNKEY]

CAS = crank angle sensor its on your timing belt cover

[ARTZ]

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?

[paulr33]

check it with a timing light at idle

should be 15deg fo rb25deg

[TwentySix]

isnt CAS - Cam angle sensor on RB series ... even though its directly related to crank angle sensor

[OMGGTR]

Correct the nissan rb engines have a CAM angle sensor which is on the timing cover but yeh i think this also does the crank .. meh

[Cam84]

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
