*cough* engine splutters! *cough*

[ix9]

Guys,

I thought i'd run it by you all first. As of about 2 days ago my car started making funny noises/jolts when on boost.

Intermittantly, over about 4000rpm with foot on the go-fast pedal, the car would cough and splutter at various points in the rev range up until redline

almost like it's running out of fuel then finding it again. all intermittantly.....

do the symptoms described sound serious ? what could they be ?

TIA.

Kym

Is it still under warranty?

Puckish,

lets not go there again!

Kym,

It could just be a injector is clogged or fuel pressure is not constant. I'd first try some injector cleaner, this should remove any deposits. I would have thought if it was a fuel pump problem then Barry would have picked it up on the dyno, so try the simple things first.

Have you bothered to regap your plugs? What gap are they at and what boost are you running?

He didn't find my still-continuing bubbling noise on boost, so it wouldn't suprise me if there's more problems.

I haven't regapped the plugs yet, that's booked in for tomorrow garage-ala-kym! I'll see what the plugs look like too.. maybe they need replacing. If that doesn't work I'll pick up some injector cleaner too

I'm still on standard boost by the way, haven't had any higher than 7psi *sniff*sniff*

Thx for the advice mate

oh yeh, and nice to put a face to the name also Paul!

Kym,

Gapping the plugs is easy, I have mine at .7mm that way you can be sure of a good spark. It does sound like the plugs may need replacing, if you use octane booster alot then they definately will.

Hope it goes well, keep us informed.

Your car looked sweet last night by the way.....

Your problem sounds like spark plugs.... I think they are ROOTED.... if you are running standard boost (7 psi) you do NOT have to regap them .... but it is advisable....

I dont think the problem is the gap.. i think they just might be stuffed....

if you use ocate booster they stuff really screws up your plugs......

just hope its not your coils ... they are a tendency for going shit on the RB motors......

Good luck Kym

I would definately have a look at your plugs. a new set of NGK BCPR6ES are less than $20 from marlows, and are gapped to 0.8mm already. They even reduced detonation on my car when I did the change, and aren't brain surgery to put in yourself.

im no mechanic, but...id check the fuel filter...some of the crap that is our fuel these days:mad:

Kym,

When I was playing with my boost i had the same problem, and it was the plugs, mine are set at .8 and running sweet.

Thanks buddy. LOVED your car too btw nice sounding BOV too... luvin it *drool*

After some body mods it'll look alot better (read: ultra-wide GTR wing, some skirts, and a S2 front bar (for FMIC))

Okay, so i'll be replacing the plugs tomorrow. That should help. I'll let you know how it all goes then

So i replaced my plugs now it runs well sweet.... even 2 years later

[dan_the_man]

I was wondering how u went

[blackanator]

Just wanna aska qu.

Did the sputtering only happen when the car was used at the start of the day, say if you drove it the night before, then to work again say 8-9 hours later, it would do it, then eventually 'fix' it self gradually about 5 mins later etc?

[ix9]

Nah it was constant.... even worse when the engine was hot

[MirKz]
