Cefiro Running real bad

[Fidel04]

hey guys, got a standard rb20 auto cefiro, under full load it just coughs and farts, and sounds like its fluttering, but its going nowhere!

any ideas?

sound like a dead air flow meter to you guys? cos i have tried 2 with no improvement!

the problem is worse when its warming up, where it does it even on 1/4 throttle

I think you need to be more spacific with the issues, eg how old are your plugs, what is their gap and what kinda boost are you running. I am guessing ignition (coils, plugs etc etc) here but that is just a guess???

[Fidel04]

runnin stock boost it still happens, plugs are about 5000km old .8mm gap BCPR6ES or something like that

plugs and coilpacks all seem fine...

Stop doing skids with it Phil, that might help

But maybe fuel filter also, something along those lines.

I still say stop doing your normal skids

[Wazz]

daveo thats a bit hard for him.. he just has the bad bogan habbits.. do skids everywere and anywere how longs it been since you chagned your fuel filter? change that.. see if it still does it

[Fidel04]

ok i have replaced fuel filter, fuel pump, ignitor module, all 6 coil packs, all 6 plugs, AFM and o2 sensor and still no success!!!!

[dangerous_daveo]

Dude, try putting stuff on that you know works again, and resetting the ecu.

Other than that, the engine could be RS by now???

[GunMetalR33]

your ECU could be Phucked...

[Fidel04]

jus replaced CAS and loom from ignitor to coils, still no success

Has it got enough power to fire the ignition properly?

Long shot but alternator might be dead - get the electricals checked.

Also check ECU isn't in limp mode for some reason it could be mega rich n retard for some reason or another but if the ECU is limpin it then atleast you have a better idea where.

Could be anything, leak in the cooler pipes? .. good luck tho.

Could be inlet leak as above person mentioned.

My inlet manifold gasket blew on firewall side underneath and couldnt be seen. Same symptoms as you and was also worse when not at full temp. I guess because as the metal heated up and expanded it closed the leak down a bit.

[Fidel04]

yeh i have busted an inlet manifold gasket once before, however last time it just would not rev past 5000rpm at all!

[RBSH1TBOX]

the cause of this problem is easy to pinpoint. For starters you drive an ex taxi piece of shit, that probably has clocked the speedo around a couple of times on the poor old 'de' so really you will be chasing your tail forever with the rb snotbag trying to find the problem. Go down to your local servo, fill up a 20litre jerrycan and set fire to the **** !!

Is it running as if its in cold start mode? Could be a busted temp sensor?

[Fidel04]

ive tried temp sensor, afm, ignitor, coil packs, plugs, coil pack loom, ecu

so many of us seem to just be living with this problem

its even apparent on stock boost!

[lwells]

Have you hooked up a consult cable to check all the sensors/diagnostics?

LW.

[Fidel04]

no i havent done that yet, i have run ECU diagnostics but!

[NZM.031]

it doesnt have a boost leak?? my 33 wouldnt rev past 5000 on any boost, took me ages to find it, i alot of parts like you have, only to find i had a split intercooler hose, real prick to see. boost would show correctly on the guage, it didnt show i was losing any, thats why i didnt think it was a leak... usually its just a simple little problem.

cheers

yeh cooler pipe leak was my first thought, but i replaced all rubber hosing and the physical cooler and made no difference
