Yeah fuel pressure is fine, fuel pump is fine.
Its gotta be heat related, cause it runs perfectly fine before it gets too running temp. -
Yeah mate plugs are new, and the ones pulled out looked good aswell.

Hey man, just all of a sudden happened.
-
Okay. I have a r33 4 door sedan.
My car has this problem, its very hard to explain so bare with me.
When the car is cold, it runs smooth and the car feels normal.
But when the car gets warm, it feels like it looses power.
When the car is cool, i can rev it and it will rev freely like it should.
But when it gets warm, ill put my foot on the accelerator slowly and coughs and farts a little bit and it will stop at about 2k rpm.. while my foot is still going down slowly the revs stay at 2k rpm, and then will SOMETIMES all of a sudden just rev through it OR if i get my foot to the ground, it will start revving between 1k and 2k rpm.. just back and forth.
So all this is usually when i get the temperature around 70 C. If it falls under 70 C, it will not do it.. so i know its heat related.
But when you get it warm, you can still get it past it, only if you put your foot straight to the ground and not slowly.
Now the ignitor gets quite hot..
When its warm, and im trying to rev it.. the lights are dimming and brightening like they are not getting enough power, like headlights, tail lights, dash lights, cluster, every light is dimming and brightening.
Ive checked the coilpacks, its surely not them.
It would not be the injectors, because they do not act different upon heat do they? and it floods when hot if i keep my foot down when its doing the revving between 1 and 2krpm.
It has a MAFless tune, so does not use a AFM.
Has anyone ever had this problem?
Its such a confusing thing to try and diagnose. -
haha okay dude thanks.
-
Okay, well my mate who is mechanic said...
"It sounds like a bad plug, or a weeping injector.. More so injector because if its revving clean when on boost it sounds like 1 cylinder is getting a tiny flooded from the weeping injector and is sorting itself out when high revs".
Does that sound right? -
Nah buying it off a random dude, but my mate owns one so can help me with it when its actually in my hands. |
So having him is a bonus.
But yeah, thanks dude

Hey superben, not sure if you're trying to say we are idiots or if you are actually saying its good..
But nah, i know jack shit about RB's.
I told him i dont know much about them, my mate does who is helping me and ive learnt a little bit.
But nah he's gonna fix it and then give it too me. Im just trying to help him fix it, by asking around seeing if anyone else has had many problems. -
Ahh okay man. If there is a Vac leak, would there be an error on the ecu as such?
Like a code or something? -
Is there much work, or much of a cost to fix this?
-
Ah okay, so you definatly think it is a Vacuum leak?
-
Mind you, this car has been sitting in a padoc for 6 months plus.
It has old dirty fuel in it.
Its not at my house though yet, i only recently just bought it. But the guy is trying to fix it for me before it comes to mine.
Would old fuel, and old fuel filter make a difference? -
Oh really?
Have you had this issue before? -
Hey guys.
im new to the "SAU", im just wondering if i could get a little bit of help, sorry if the thread is in the wrong spot, feel free to move it.
But, i have a r32 gtst with an rb20det.
It has a rough idle, but when you rev it and its on boost it revs cleanly.
Has anyone had this problem before?
Any ideas on what it is?
I have a feeling its an injector or something :\

Its a wolf 3d one. The ecu has no errors.
It got worse and ran on 5 cylinders, and it sounded like a subaru, so we replaced the ignitor loom, ignitor, rechecked all the coilpacks and injectors AGAIN.
It fixed the subaru problem, but still when she gets warm it acts the way I described it in the post.
Only thing we have now is to replace the alternator, and check the coolant temperaure sensor..
Otherwise im out of ideas.
